I surmise then that filling spaced armor cavities with fluids (fuel or otherwise) is not worth the trouble, compared with just leaving air between the plates, since it'd cause a rather consequent increase in weight? I remember (from AW's forum, some time ago) some Soviet tanks having those turret cavities filled with some sand/concrete-like matter. Does it merely absorb shockwaves or slow down KE projectiles, or does it have some sort of abrasive effect on penetrators (whittling it down or simply deforming it) and such?

Are there any known stats about the performance of fluids (either liquids or gasses) against CE/KE? I know the Israelis did some testing a while ago and determined that fuel could actually disrupt HEAT jets somewhat, but I'm curious as to how well it mitigates threats.

I'm perplexed by USAR/GDLS's decision not to coat the inside of the crew compartment with a spall liner (the only reference to spall protection, in Hunnicutt's Abrams book [p.209], refers to the three 105mm rounds stored on the basket floor, which were covered with "spall protection covers"). Were the engineers so confident about the protection the Abrams already boasted, they neglected such a feature (and just delegated the "last line of defense" to crew gear) or was this absence part of some sort of cost/weight-cutting effort? ...Or please don't tell me the SL is actually inside the armor pack boxes, on the innermost walls...that'd be a bit weird.

Well, "treatment" might not have been the correct term. More like "forging process". From what I hear it's some sort of multi-stage heating process that helps reinforce the long rod's tungsten and diminish deformation during the self-sharpening phase. The same trick was apparently applied to the K-279. And that's about all I know on the matter. :-/

The characters are of the Hangul alphabet i.e. Korean. This here looks like a K-276 APFSDS-T, made out of specially-treated tungsten to allow less deformation upon penetration.

Oh, hey, there's new information and pics compared to the original AW version. Nice meetin' ya here, Damian. (Not sure whether you'll keep going to the AW forums now that the game is tanking hard - no pun intended - and haemorrhaging members)
