Can we get a consolidation for the amount of rounds the M1A2s have to carry?
Currently:

Here’s some official unclassified documents showing the M1147 is meant to consolidate the rounds shown above:

Here’s a simple video from the official Northrop Grumman youtube channel since I’m a simple guy:
I personally don’t care about the real statistics of how “better” the round is (pentration, velocity, etc) I would like to just have one round replace these instead of having to switch between multiple rounds and getting confused since they all have the same HEAT logo.
Well, you need to have a HEAT round that can be used as a stock one. Then be able to upgrade to a better variant of that. And then be able to carry something that’s anti-heli aka MPAT (aka HEAT MP). Not really a reason to replace all three with one. There isn’t really a reason to even bring all of them at the same time. You can just bring mostly MPAT and if you really wish the better of the other two. You’ll just need to remember which one is first.
Every 12.7 brings stock APFSDS, this would just be nice to have.
what are you talking about?
no other top tier MBTs have more than 1 heat round
AMP could definitely replace M830, M830A1 and M908 for the M1A2 SEP versions at 12.7 BR. We don’t need to have a stock HEATFS round anymore at that BR and this round should be closer to smart SAP with tons of fragmentation like the Israeli 120mm HE round already in game.
Even if gaijin is still set on forcing players to have a stock HEATFS round M1147 AMP can replace M908 and M830A1 with one round.
I really do not understand the complain, people should really be grateful to have many options to choose. Also the AMP’s airbust mode its with time fuze only, while the M830A1 acts like a VT round (so rather take the second one), why would you want a downgrade?.
