I was looking at that 60mm back plate claim for the Leo2A0-4 and I can't make it fit with the evidence provided this is just at quick mock up and its not 100% accurate but you can clearly see that the points you use to measure distance from are quit a bit away from each other and because of the...

Heres an article that mentions the 3BM42 ISSUU - Arms 2010-4 light by Pavel Dem I typed out the numbers so if anybody wants them they can copy it here. Characteristics of the 3BM42 APFSDS projectile <<Mango>> Introduced in 1986 Material of Active part of the hull-steel Material of Penetrator -...

Well the weight of the M829 penetrator(tip, windshield, body, core and fin) is 4.46kg(measured from WA core of equal density) but the DU core is only 4kg. Is 4.6 the weight of complete projectile minus SABOT or the DU weight? This again seems to be point in the direction of not being a M829A1...

I don't think its a M829A1 used, mainly because here: ~4000g DU the DU mass of the projectile is given and that is the DU mass of a M829. I don't know the DU mass of an A1 but given that its vastly different I guess that the DU mass is not exactly the same.

No that is not what I am saying, the face plate is thicker yes but it goes further into the turret not sticking out. Turret dimension has not changed between IP and A2. STGN

You are right I forgot the faceplate is thicker, but the turret exterior size is the same. Still we have official document saying the added hardened steel to the front turret. STGN

This is not just spur of the moment; I have checked a lot of photos. I could have used recent photos of M1A2 but then I would be accused of comparing apples to oranges. Perhaps but you have to produce ~900 armor arrays. also why add plates to the front of the M1A1 if you already put in HAP if...

In the book "M1 Abrams vs T72 Ural" by Steven J. Zaloga it is claimed that alot of older M1A1 Abrams tanks were upgraded to HA standard protection. (M1 Abrams vs T72 Ural :56) I have been looking through most of the government studies and reports sourced by Zaloga and so far have been unable...

1760m/s at 2000m... sounds more like the muzzle velocity? STGN

The picture in the link is not at M1A2 SEP, its a M1A1 with SCWS STGN

Sorry I am mixing up old and new army structure I think.

I meant it dosen't sound like all the M1 assigned to ARNG brigades will be SEP. Only the ones in Armored brigades. STGN

This?: "Recapitalizing of 100% of the M1 Abrams tanks required in the ARNG Heavy Mounted Maneuver forces to the M1A2 SEP level of mode rnization." You sure its all M1's and not just in armored and Heavy Brigade Combat teams? STGN

The armor around the crew hatches does look to me like its removable and replaceable, a lot easier than the turret armor cavities which are welded shut. STGN

That is what it says: "AMAP-B offers ballistic protection against conventional ammunition of various calibres. Depending on the desired protection array, it conforms to STANAG levels 1-4, or STANAG level 5 in combination with base armour. AMAP-B has been certified accordingly." direct copy paste...

well the category is Vehicle/mobility, so it might be a mix of cost and mobility. Read on some forum that the Abrams was the most expensive to buy and given the higher cost for fuel this could be the reason it placed last. Does anybody have price figures for the vehicles in 1993? All the...

According to Reinmetall AMAP-B offeres STANAG level 5 protection when used together with base armor so that is protection against 25mm autocannon. I didn't say that roof protection was 1.5 times 2". What I meant was that Abrams and Leclerc has very little roof protection and so adding...

Its possible that might have an influence but I think that what they are really talking about is not the front turret or hull armor but the roof protection and spall liner, maybe side skirts and other "minor" parts. I see this as an "overall" protection % increase not that the armor in the...

Heres the paper There are two mentions of ballistic protection first is that swedish-german developed armor was between 50-100% more effective than the French developed armor in some aspects and also more effective than then Abrams armor. This part seems really unclear, they tested different...
