M4 AR firing mode innacuracies
The M4's carried by the Army have a semi and 3 round burst firing modes, not full auto. Currently, all US Army soldiers in the ACE mod carry M4's that have semi and full auto firing modes.

They are not M4's in game, they are M4A1's which are fully auto vs the 3 round burst on the M4's
