The armor is HAP-3, same as the SEPv2. The next armor upgrade isn’t seen until the SEPv3.
Instead of the M1A1 SA, with the USMC 251st Birthday coming up, add the Marine Corps last Abram’s it ever had as an event tank, the M1A1 FEP (Fire Enhancement Package)
They renamed M1A1 AIM in us tree to M1A1 SA, does this count?
What’s this?
At that point you might aswell play the M1A2 Trophy which is only 66 tons. You get a commanders, and all that good stuff on top of an APS. The draw for the M1A1 upgrades I would’ve thought Would be better HP/T.
+1 for increased Situational Awareness

With Infantry mode we could see armored vehicles get a nerf where you need to look though visual slits this would help medicate that issue.
Has anyone made a suggestion?
The AIM should be properly remodelled into an US SA and the FEP foldered under the HC IMO
