Probably rubber from sandwich plates. And remains of projectile and jet, that were stopped and contained inside special armour array. With perforated target there is no such problem, but there are few more

...and Chobham armour demonstration: https://www.iwm.org.uk/collections/item/object/1060035263 Lookes like holes were covered after firing to hide details of interior.

Fort Irwin case looks like ammo deflagration after uncontrolled fire in engine bay. Not so rare situation in case of M1s. Abrams 120mm ammo compartments are designed to withstand full detonation of one HE warhead - a bit more than equivalent of 2 kg of TNT. Other scenarios - like sympathetic detonation of more warheads - might be a lot of more dangerous for crew.

I am not sure what do you mean by 'our army' here. General staff or commands' officers? Crews? I think their opinion might vary, from none to some. But this means nothing really important. No trials of Leopard 2 protection were ever conducted in Poland. And no trials of K2 and M1A2 protection were ever conducted in Poland. Decision to buy those tanks got nothing to do with any factual knowledge about protection level of those AFVs that 'our army' might have. More, that decision do not have much in common in 'our army' opinion, nevermind as you define it. Please, do not use example of Poland's last decision as argument. In Sweden and in Greece a lot of trials were made, so decision could be taken with some knowledge in min, not opinions.

Well, you invoked it as an argument. It is not very fair to turn Piotr's claims into 'some time ago somebody wrote something somewhere, go and find yourself'. Maybe it would be easier for you to mark those errors? Or make an answer to methos post, which looks like quite well supported.

I asked about errors, which according to you those documents were full of. Fragments provided by methos sounds reasonable. Do you have strong evident that "Swedes could only guess"? I am affraid I missed that content by Piotr. Was it on the web or printed in "NTW"? Did Piotr make a claim that M1A2 was anyhow treated unfavourably by Swedish researchers?

Damian, could you indicate main errors in Swedish documents and elaborate why you disregard data on M1A2 included there?

In general, single-pin pros: - simplicity - low weight - price and cons: - easy access of dirt into pin mounting can result in faster erosion and track lengthening - excess load on pin can result in pin deformation - polygon effect that can result in excess vibrations - noisy. Double-pin pros: - longer life - lower vibrations - easier maintenance - smoother and quieter ride and cons: - complicated - heavy - expensive.

Almost. XM735 got different fin section, was a bit longer. Final 105 mm design - M735 - was further changed and visually differs from XM579 and XM578. Check BOCN forum for some pics and schemes.

Awesome! I am enjoying it a lot, thank you! For side note, predicted performance of XM735 (early model, based on XM578, but before core was enlarged in XM735E1) versus bar reinforced 5" armor was 1000 m, versus double target was 3000 m and versus triple target - 1000 m. Docs from 1973,

'Chobham Armour: Cold War British Armoured Vehicle Development' by William Suttie, 2022. Waiting for a copy, but his 'The tank Factory' was a good read.

Looks like Patriot DVE AN/VAS-5B(V).

Great material.

Looks like it found a mine. Also external ammo magazine in turret bustle was on fire (caused by mine explosion or different impact?) and worked as designed. Probably one of the blow-up plates can be visible on the ground there.

In case of Abramses there was a number of various accidents when drivers got injured or killed. Some drowned, some crushed by rotating turret (this is why driver's hatch safety interlock was introduced in M1A2s and then in M1A1s). There were some nasty fire accidents because of faulty NBC protection system, with carbon filters installed in nearside of driver station played it's role. AFAIR there were also some accidents in Iraq with Abramses and Bradleys falling into canals - I recall I read about two such, with 4 and 6 KIAs, respectively. Beeing a member of armour crew seems to be dangerous sometimes.
