The First Time As Tragedy, The Second Time As Farce

Saturday, October 7th, 2023

Hamas decided to celebrate the 50th anniversary of the Yom Kippur War by launching another war.

Israeli prime minister Benjamin Netanyahu declared “we are at war, and we will win it” early Saturday as the country’s air force began striking targets in Gaza in response to a surprise Hamas attack on the 50th anniversary of the 1973 Yom Kippur War, involving more than 3,000 rockets and groups of terrorists descending on Israeli territory by land, sea, and even paraglider.

At least 40 Israelis have been killed in the fighting and at least 740 injured, the Israeli military said, and videos posted on social media appear to show Hamas taking civilian hostages. A militant group in Gaza, Palestinian Islamic Jihad, also claims to be holding a group of Israeli soldiers hostage.

As rockets rained down on central and southern Israel, the televisions began broadcasting footage of armed groups of Hamas terrorists pouring into towns across the country in pickup trucks, the Times of Israel reported. In response, the IDF deployed forces to the south, where troops began engaging with the Hamas invaders.

The Israeli Air Force also scrambled dozens of jets to strike four command centers and 17 military compounds in the Gaza strip, the air force announced on X. At least 198 Palestinians have been killed and 1,610 have been wounded in the retaliatory attacks, according to the Palestinian Health Ministry.

The biggest difference between the real Yom Kippur War and Hamas’ farce is the size of of the opposition. In 1973, Israel was attacked by the armies of Egypt and Syria supported by forces from Saudi Arabia, Algeria, Jordan, Iraq, Libya, Kuwait, Tunisia, and Morocco, plus some random units from Cuba and North Korea, a coalition that theoretically could wipe Israel off the map. By contrast, Hamas is a terrorist organization that controls some 141 miles of square territory and survives on handouts from the UN, EU, Iran and Syria.

Israel has the most modern and technologically advanced army in the Middle East, and arguably the second most technologically advanced in the world. Their air force is entirely American-made, including F-35s.

The news that Hamas is using technicals is both interesting and obvious, as they’re a very cost-effective option. They’re not ideal for urban combat or stand-up fights, but if they can get out of the built-up area around Gaza and out into the flatter, more open terrain to the south they can do some damage as hit and run forces, at least until the Israeli Air Force can track them down. I assume Hamas has drones, because it’s 2023 and everyone has drones, plus their patron Iran makes some.

Enjoy some random combat footage, including what looks like a knocked-out Merkava tank.

We all know what the outcome of this conflict will be: Hamas will kill some Israeli civilians and a few IDF soldiers, and Israel will pound the snot out of Hamas and it’s command and control infrastructure, after which it will take Hamas a decade or so of payments from its sugar daddies to build up enough to do it all over again.

Hamas is a pustule that occasionally needs to be lanced, but little more.

Update: Yep, drones. IDF needs to go back to the makers of Trophy and ask why it didn’t stop a slow-moving, top-drop munition.

Tank News Roundup for July 29, 2018

Sunday, July 29th, 2018

There’s been just enough news about tanks lately to make a roundup worthwhile:

  • Israel introduces a new tank:

    Israel is developing a new, Artificial Intelligence-equipped version of its Merkava tank that is also designed to fight in cities.

    Israel’s Armored Corps likens the Barak (“lightning”) to the Israeli Air Force getting the F-35 stealth fighter.

    The Barak, an advanced version of the current Merkava 4 tank, is scheduled for deployment by 2021. “The Merkava Mk. 4 Barak will be the first tank to have a smart mission computer that will manage the tanks’ tasks,” according to an Israel Defense Forces announcement . “This advanced artificial intelligence will reduce the team members’ workload and help them more accurately locate and strike targets.”

    In addition, the Barak will have upgraded sensors, networking with other tanks, and a Virtual Reality system embedded into the tank, which the crew can access via special helmets. The VR equipment will allow the crew to perceive the environment around the vehicle, as well as conduct virtual training and mission rehearsal inside their tank rather than having to travel to a special training center.

    “The helmet is called Iron View, and it will allow the combat soldiers to see the outside environment from inside the combat vehicle,” said a senior Armored Corps officer. The Barak will have systems to warn the driver of obstacles, similar to those found on luxury automobiles, as well as an active protection system (presumably the Trophy anti-missile system), an IDF commander told Israel’s Walla news site. The tank will also have improved logistics that will enable it to carry out missions that are 30 percent longer than current operations.

    Most interesting is the Barak’s new target. Tanks traditionally have been designed to fight other tanks, or provide support to infantry, on a regular battlefield. But the IDF has designed Barak for urban warfare, especially against insurgents such as Hamas. During Operation Protective Edge, Israel’s 2014 incursion into Gaza, Israeli troops found themselves embroiled in fierce street fighting — including Hamas fighters popping up from tunnels — on a confined battlefield where enemy combatants and civilians were mingled.

    Snip.

    The 65-ton Merkava is a unique design built around Israel’s needs, in particular the overriding desire to protect the crew from harm. The engine is in the front of the vehicle, which provides additional protection, while the rear has an armored compartment to carry up to eight infantry or three stretchers. The Merkava 4 is armed with a 120-millimeter cannon and the Trophy active protection system, which fires a barrage of shotgun-like shells to destroy incoming anti-tank rockets.

    The Merkava’s rear door also facilities rapid resupply of cannon rounds, which the Israel found to be a particularly pressing need after many tanks ran out of ammo during the course of the Six Day War. The 120mm main cannon is a smoothbore, very similar to the Rheinmetall M256 120mm smoothbore cannon mounted on the M1A2.

    Here’s a not-completely-useless video on it that pulls some of the VR clips from the IDF video linked from the National Interest piece:

  • Speaking of the M1A2, to counter a possible Chinese invasion, Taiwan is buying 100 of them to replace Taiwan’s aging tanks (presumably M48s and M60s) at a cost somewhere between $650 million and $1 billion.
  • Short piece comparing the American M1A2 and the Russian T-14 Armata. There’s not much new here if you’ve already read my write-up on the T-14.
  • Speaking of which, here’s an American tank crew talking about the T-14:

    “T-14’s got a three-man crew,” one specialist said, sitting behind the .50-caliber gun atop the Abrams. “All the crews in the hole, so it sounds pretty safe.”

    The specialist zeroed in on the T-14’s autoloader.

    “You looked around in here,” he said. “You see how sandy it is? You need something that’s going to work in all terrain.”

    “Generally, I think the Russians like to build things that — like the AK, you can throw it through the mud and it’ll keep shooting,” the specialist said. “I feel like with the T-14, they got their eye off the ball, trying to be fancy.”

    The specialist also said a crew member could load the cannon faster than existing mechanical autoloaders — so I asked what the point of an autoloader was.

    “If the ammunition is so heavy, and so long — it’s a small turret here,” the specialist said. “The T-14 has gotten around that by having an entirely automated turret. What happens, though, if something goes wrong in the middle of battle, and somebody’s gonna have to get up in there, get out of their position? I don’t know.”

    “Let’s say there’s a misfire,” another crew member interjected. “How much work would it take to get that machine open, get that breach open, and get down in there?”

    I then asked what they thought about the idea that the T-14 could eventually be an unmanned tank .

    “Maintenance-wise, an unmanned tank is going to be really difficult,” the specialist said. “All I do is maintain tanks … and these tanks still go down.”

    Despite unveiling the tank in 2015, Russia has still not mass-produced the T-14 because of the high cost of the platform. Moscow initially said it would produce 2,300 T-14s by 2020 , but last year, it said it would make only 100 in that time.

    Not sure I agree on the autoloader speed part. Industrial automation has gotten plenty fast, so there’s no reason a properly designed autoloader wouldn’t be faster than a human crew. Whether the Russians got it both fast and reliable enough for all-terrain combat situations is another matter…

  • And here’s a piece on how China’s Type 99 tank stacks up against American and Russian tanks:

    China’s Type-99 combines a hull that closely resembles an elongated T-72 with a Western-style turret inspired in part by the German Leopard 2. First appearing as the Type 98 prototype tank in a National Day parade in a 1999, the vehicle was re-designated the Type 99 and entered service in 2001. At 57 tons, it comes in between the 70-ton Abrams and the 48-ton T-90 in terms of weight. Several upgrades, including the new Type 99A2 variant, boast advanced new technologies. Beijing fields nearly 500 Type 99s in sixteen armored battalions, and has produced 124 of the newer 99As so far. The type is not offered for export, though some of its technology is used in China’s VT4 export tank.

    The Type 99 and the T-90 rely on a 125 millimeter cannons using carousel autoloaders descended from Soviet-era designs. This weapon proved underpowered verses Abrams and Challenger tanks in the Gulf War, but new improved tungsten ammunition leaves it capable of piercing the frontal armor of an Abrams at shorter combat ranges.

    The new Type 99A2 comes with a longer barrel main gun, which in theory should impart higher muzzle velocity to sabot shells and improve their armor penetration and accuracy. It also boasts fancy new stabilizer technology.

    Reportedly, China intends to eventually install a larger 140 millimeter gun on the Type 99, but early tests have cracked up the weapon. This, incidentally, mirrors Russia’s plans to up-gun its new T-14 Armata tank to a similar caliber weapon.

    China has developed its own depleted uranium ammunition for its 125 millimeter gun, which it claims can penetrate the M1 up to ranges of 1.4 kilometers.

    The Abrams uses a fourth crewmember to load the gun, which American tankers argue is more reliable, offers a higher rate of fire, and gives the tank a spare hand if one of the other crew members is incapacitated. However, the space needed to accommodate a fourth crew member makes the M1 larger and heavier.

    The Type 99 and T-90 both can fire anti-tank missiles from the gun tube, while the Abrams cannot. (The Type 99 uses AT-11 Refleks missiles licensed from Russia). This could theoretically be useful for combat at very long ranges, or against low-flying helicopters. However, tank-launched missiles have existed for fifty years without seeing much use.

    Effective sensors for spotting and aiming are arguably as decisive in tank engagements as firepower. Russia has made some strides in tank sights and thermal imagers in recent years, though the general sentiment is that Western sights and sensors remain superior. The T-90A does not carry Russia’s best hardware (some have been upgraded with French Catherine thermal sights), while the T-90MS has an improved Kalina targeting system.

    China is known for its excellent electronics, and the Type 99A2 supposedly carries a new infrared tracking system that enables it hunt enemy tanks efficiently and is believed to be superior to the systems on the T-90A.

    The Type 99 benefits both from composite armor, and Explosive Reactive Armor (ERA), bricks of explosives onto the tank that prematurely detonate incoming shells. The new Type 99A2 variant uses a multi-layered system thought to be similar to the Relikt ERA developed by Russia, which uses a radar to detonate the ERA before hostile shells impact. It is intended to defeat tandem-charge missiles capable of overcoming older-generation ERA.

    The T-90A uses the older Kontakt-5 ERA, while the new T-90MS tanks serving in India sport the Relikt system. Though most effective against anti-tank missiles, both systems also diminish the penetrating power of tank shells.

    The Type 99 also comes with a Laser Warning Receiver which warns the tank commander if his vehicle is being painted with hostile targeting lasers, affording the driver a chance to back away out of danger. Given all the videos from Syria and Yemen of tanks sitting obliviously as anti-tank missiles meander towards them (often taking 20 seconds or more to impact), this could significantly improve survivability.

    The Type 99 also is believed to come with its own unique high-powered ‘dazzler’ laser designed to jam laser- and infrared-guided missiles, damage enemy sights, and blind the eyes of hostile gunners, possibly with a permanent effect. Fortunately, high-power tank-mounted dazzlers have never been used in combat before, so we have no idea how well they would work.

    The Abram’s Rheinmetal 120 millimeter gun, equipped with politically-controversial M829 depleted-uranium rounds, can penetrate around 15-25% more armor. The U.S. now produces new generations of M829 rounds capable of piercing the advanced Kontakt and Relikt reactive armor systems developed by Russia (more on those below).

    All interesting stuff, but the author loses me here:

    The M1 Abrams lacks its own Laser Warning Receiver, Active Protection Systems or Explosive Reactive Armor, though it is conceivable future upgrades will incorporate some of these features.

    Umm, no. Though not standard on every tank, the the Abrams Reactive Armor Tile package has been an option since 2006. To say the M1A2 lacks active protection right now is technically correct, but upgrading tanks with the Israeli Trophy system is already in the FY2019 budget.

    The author’s observation that the Type 99 is faster and less gas-guzzling than the M1A2 is, alas, probably accurate.

  • Instead of retiring the T-80, Russia is upgrading it:

    In 2017 the T-80BVM, a deep modernization of the T-80BV, was revealed to the public. This included the new standard Sosna-U thermal sight, a new Relikt explosive reactive armor (ERA) fit and a general overhaul of the chassis, bringing the T-80BV up to the standard of the T-72B3.

    The T-80BVM is even superior to the T-72B3 in some aspects, as the ergonomics of the gunner’s station are said to be better than the B3 as the Sosna-U station is placed directly in front of the gunner as opposed to off to the side on the T-72B3. The superior characteristics of the T-80BVM have resulted in it being assigned to the elite 4th Guards Tank Division “Kantemirovskaya” instead of T-72 or T-90 variants.

  • Canada is having trouble find a good home for its retired Leopard C2 tanks. While I would be happy to take delivery of one, I suspect the cannon muzzle would stick out in the street, and I fear the tank’s weight would degrade my driveway. Plus there are all those pesky federal regulations… (Hat tip: Ace of Spades HQ.)
  • Update: This is curious:

    A Look At Russia’s New T-14 Armata Tank

    Thursday, August 20th, 2015

    Last week was almost Russian Tank Week on BattleSwarm, but a plethora of news intervened (like Vladimir Putin intervening in the affairs of neighboring states).

    But one interesting tidbit I didn’t get to was the fact that Russia has introduced a new generation of tanks (and mechanized fighting vehicles more generally, all based off the same base platform).

    So is the new Russian T-14 Armata main battle tank something to worry about, or does the M1A2 Abrams retain clear technological superiority?

    To my very, very outsider eyes, the answer is somewhere in-between.

    First the description from Jane’s:

    The T-14 is Russia’s first truly new tank design since the T-72, designed in the early 1970s. Based on the Armata Universal Tracked Platform, the T-14’s most attention-grabbing feature is its unmanned turret, with all of the MBT’s three crew (commander, driver, gunner) seated in a well-protected crew compartment at the front of the hull.

    Notably, the unveiled turret dispels suggestions the MBT would be armed with a coaxial 30 mm cannon, in addition to its 2A82A 125 mm main gun. Indeed the pre-production vehicles paraded by Russia feature neither a 30 mm cannon nor a coaxial machine gun (MG) armament as expected, although the production vehicles might eventually feature the dual 30 mm cannon/7.62 mm MG.

    Although the T-14’s turret features a large bustle, it remains unclear whether this features the autoloader/weapon-handling system for the MBT’s main gun or serves another purpose (meaning the T-14 would retain the vulnerable hull-mounted carousel system present in previous Russian MBTs). Some reports also indicate Russia has not entirely abandoned its ambitions to arm Armata with a 152 mm main gun. If this is the case, it could explain why the T-14’s unmanned turret has an unusually high profile relative to the position of the 125 mm main gun, with the turret possibly designed to incorporate growth potential up to the 152 mm calibre.

    T-14 is armed with a remote-controlled turret (RCT) armed with a 7.62 mm PKTM MG, with the unit also functioning as the commander’s independent sight. The gunner’s sight is mounted to the left side of the main gun and shielded by a two-piece armoured door to protect it from small arms fire. A barrel reference unit is mounted above the base of the 2A82A main gun, which notably lacks a fume bore extractor (which would be superfluous given the turret is unmanned). Metrological, satellite communications, GLONASS, datalink, and radio communications antennae are fitted on the roof of the turret.

    The MBT’s turret is literally covered in a variety of launcher and sensor systems understood to be linked to a new APS system, which some reports call ‘Afghanit’. At the base of each side of the turret are five large and fixed horizontally arrayed launch tubes covering the 120° frontal arc of the turret. These bear a strong resemblance to the launchers for the earlier Drozd and Drozd-2 APS, which fired a hard-kill 107 mm unguided projectile armed with a high-explosive-(HE) fragment warhead to defeat incoming anti-tank guided weapons (ATGWs).

    The T-14 is also fitted with four sets of smaller-calibre launchers, with each unit armed with 12 launch tubes. Two horizontally trainable launcher units are fitted on either side of the top of the turret, while two apparently fixed and vertically facing launcher units are recessed into the top of the tank’s turret.

    It is unclear whether this second system fires hard-kill (ie warheads) or soft-kill (ie anti-infrared/laser-obscuring smoke) munitions, or a combination of the two. It is also unclear if the vertically mounted units are fireable, or simply storage for reload units for the two trainable launchers. One limitation of the Drozd systems were that they provided no protection against threats emanating from above the tank, so mounting the fixed launchers vertically could be one way to provide protection against top-attack threats.

    Providing warning and guidance for the APS system are two types of sensors mounted around the T-14’s turret. Two large sensors, believed to be electro-optical/infrared (EO/IR)-based laser warning receivers, are angularly mounted on the front of the turret providing 180° coverage, while four smaller sensors (covered but believed to be radars) are mounted around the turret providing 360° coverage.

    Armata features a notably different hull design to the T-72/90. One striking difference is the road wheels, which are of a different design to the T-72/90’s, while the Armata features seven road wheels, to the six of the previous MBT designs, with the drive wheel at the rear. This is similar to the T-80 MBT family, which also has chassis with seven smaller road wheels.

    It is not known whether Armata is equipped with a gas-turbine or a diesel engine [given how the Russian chain of command swore off gas-turbine engines after the T-80’s performance in the first Chechen war, probably diesel. -LP] , but the T-14’s powerpack is mounted at the rear of the MBT, with two internal fuel tanks mounted on either side, and exhausts also mounted on either side. Day/night cameras are mounted around the T-14’s turret to provide situational awareness, while a forward-looking EO/IR (FLIR) system is mounted on the front of the hull for the driver. The driver’s hatch has no periscopes. When driving buttoned-down, the driver may be in a reclined position, using a set of periscopes mounted on a second hatch directly behind him.

    NII Stali is understood to have designed a new form of steel armour for the Armata family. Speaking to TASS, a NII Stali representative said the “steel armour alloy, named 44S-sv-Sh [44S–], is approved by the Armata’s developer. The alloy’s operational testing has been started and it can be used in prospective vehicles’ parts”. The use of the 44S-sv-Sh steel in Armata is intended to provide protection at a similar level to STANAG 4569 (first edition) Level 5. The high level of 44S-sv-Sh’s protection is ensured by the short-grained material structure, the optimised legation process and the special heat processing. The steel has also been designed to maintain its characteristics in very cold conditions.

    The Armata design is also understood to utilise explosive reactive armour (ERA) within its base design (rather than the appliqué ERA tiles seen on previous Russian MBTs), with views from above the MBT showing a distinctive tiled pattern indicative of ERA on the top of the vehicle’s chassis and turret. Although what appear to be ERA tiles are present on the turret roof, much of the sides of the turret appears to be just a thin cladding covering the various APS and sighting systems rather than armour. Appliqué armour (unclear if passive or ERA, or both) is fitted to the forward two thirds of the T-14’s sides, while the rear third is protected by bar armour to provide clearance for the T-14’s exhausts.

    Here’s a picture of the front by way of NPR:

    I’m not going to get into the electronics/sensor/packages, since it’s all devil-in-the-details stuff impossible to evaluate at this point. (The active protection system could be very interesting, but there’s no way of knowing how it stacks up to Israel’s Trophy or the still-under-development U.S. Quick Kill.)

    The big reasons I think the M1A2 retains overall superiority:

  • “NII Stali is understood to have designed a new form of steel armour for the Armata family.” Unless this new steel armor has radically improved properties, it seems unlikely to be even as effective against HEAT and/or kinetic penetrating rounds as the Chobham ceramic composite armor used by the M1 and British Challenger tanks, now into (at least) its third generation.
  • I do not like the shape of that turret. At all. Way too high profile, though up-gunning to a 152mm cannon (which I’m skeptical they can do effectively, even with this huge turret) might make it a more acceptable trade-off. (Early T-14 mocks showed a radically low profile turret that evidently turned out to be a pipe dream.) The degree to which the turret bulges out over the side and rear seems like shot traps. That flat section to the right is evidently a gunner sight, which looks like it’s just asking to be targeted. (Then again, the T-72 used this weird stacked bulging steel plate system to provide “non-ractive reactive armor”, which might alleviate the problem some.)
  • Not seeing any detailed information on the Russian fire control system for the main gun. If there were radically improvements you would expect more crowing and demonstrations to the press for the export market, which I haven’t seen. Since the M1A1 was achieving kills against Soviet armor at the extreme range of its fire control system back during Desert Storm, I’d need a lot of evidence to be convinced the Russians have caught up, and so far I don’t see any.
  • That said, there are a number of interesting features on the T-14:

  • The fully automated turret. It’s no surprise that the Russians went in this direct, since the T-72 already used an autoloader. (There were persistent rumors that the T-72’s autoloader had a nasty tendency to rip off crewmen’s arms, but the consensus out on the web seems to be that this is probably untrue.) With the constant march of progress there’s no reason you couldn’t have a reliable auto-loader, and I wouldn’t be surprised to see future American tanks take this direction.
  • The 125mm smoothbore cannon, which should theoretically outgun the 120mm on the M1A2. (Cue Nigel Tufnel: “Well, it’s 5 bigger, innit?”)
  • The top speed is reportedly higher than the Abrams, somewhere in the 50 MPH range, which seems quite likely, given that the Abrams is the heaviest modern MBT in current service. However, the T-14 engine may have some reliability concerns:

  • Integrated reactive armor: Probably a net plus. Like the TUSK package for the Abrams, I suspected this was developed in response to specific experience with asymmetrical urban warfare (in Russia’s case in Grozny, where the T-80 performed very poorly). While I have my doubts that the T-14 can defeat modern two-phase top attack anti-tank missiles like Javelin, it’s probably more than adequate for defeating the average Joey Jihad RPG. The concern is that while reactive armor certainly increase vehicle survivability, it’s very hard not to let it increase fratricidal lethality to nearby friendly infantry. Then again, Russian military doctrine has always had a callous attitude toward infantry casualties…
  • Maybe the integrated roof launcher array can defeat top attack anti-tank missiles like Javelin and RPGs. Hard to gauge effectiveness without seeing how it performs in actual combat.
  • I like the wide access door at rear, which reminds me of the rear doors Israel designed to the Merkava after the experience of running out of ammo during the Yom Kippur War. (I’m less wild about the high, relatively exposed positions for the gas tanks at the rear of the vehicle, something the bar armor only partially alleviates. But it might be an acceptable tradeoff.)
  • All this assumes that significant numbers of the T-14 actually get built, given that Russia has cancelled at least two separate tank programs (Black Eagle and the T-95) to follow on to the T-72/T-80, and that their economy is really biting the yak in the wake of the oil price collapse and Ukraine sanctions. But the shared Armata platform probably helped reduce development and production costs, and I suspect it will get put into production, as a big new main battle tank seems like exactly the sort of thing Vladimir Putin likes seeing built.

    This is just a quick overview based on limited information. Those with more information and/or deeper subject knowledge are welcome to sound off in the comments.

    Update: Missed this Jane’s update on the T-14’s armor.

    The base armour on the new tank consists of metal-ceramic plates. Novosibirsk-based company NEVZ-Ceramics has already launched serial production of this product, according to Andrey Nikitin, the head of the company’s armoured ceramics bureau. “We finished the trials this year and the elements revealed their declared capability,” he said.

    Nikitin said the new metal/ceramic armour provides one-and-a-half times more resistance than fully metal systems.
