@TheCompton73 Possible, but due to the breakdown and fact that the no pats are not the US, then they could be using cheaper, easier to source (and probably older surplus) rounds.
Of course it is also possible that they could develop something far better that we have not even considered.
@Flavin913 As they are fighting for both sides, then the US are only supplying one team, the Russians are supplying the other.
However they also have their own equipment, remember the ship from the prelaunch movie and the weapons they obviously had before being forced to choose a side. No pats have been split to fight on both sides in 2042 and some arguably would change as they see the benefit.
