I dusted off my account here just to say I think you've done a fantastic job with this mod. Thank you so much for going the extra mile and making sure everything works smoothly for ArmA 3.
I saw a couple things that other folks have already mentioned, but I don't know if anyone's noticed that the commander's 12.7mm MG on the M1A2 Tusk 2035 sounds the same as its 6.5mm coax, but it sounds beefier on the M1A2 Tusk and M1A2 Tusk Tan.
Compared to the MBT-52 Kuma and M2A4 Slammer UP, the M1A2 Tusk and M1A2 Tusk Tan commander's MGs sound the same. However, the M1A2 Tusk 2035's commander MG shares the same sound as all of the other tanks' coax guns.
One thing I thought odd, which isn't due to this mod, is that Bohemia used the same sounds for both the 7.62 and 6.5mm coaxial guns. In the meantime, this results in the M1A2 Tusk 2035 having the same weapon sound for the 6.5mm gunner's coax, 7.62mm loader's MG, and 12.7mm commander's MG.
This doesn't detract from what I think is an otherwise solid mod, I just thought I'd make the observation. Again, thank you very much for putting the work in and providing this to the community.
