Its not fair to summarize the points Ive made like that, its a straw man argument. Ive already told twice that its not about oneshotting every opposition, its about defeating Kontakt 5 in the hull. Not even the turret, just the hull. That means the T80BVM or T90 would still be immune to it, since they have relic, but tanks at 11.3 or below would be easier to kill. Dont know if it would affect the Leo or 122s, but I doubt it, since the ammunition isnt designed to defeat these tanks.
Other nations have other things going for them like better armor at the leos or higher T Series, the Challenger should be included here too but isnt well protected in its current state, so having worse armor but better killing power against certain vehicles shouldnt be a big deal.
Understandable. I still think better ammunition would help the US to get more on par with the current top nations, and the A3 needs to come anyway, maybe with the SEPv3, which would then lead to more seperation to the lower ranks, where that kind of ammunition would be too OP.
