Is it really 1 G43 or more? Because they now seem like snipers. You can't close in with infantry to kill them, plus in mid range combat, they also beat Riflemen. At least that's what i experienced since the new patch went live.
They get one transferable normal G43, and -10% received accuracy and -15% weapon cooldown. It's an upgrade that costs 60 munitions and 30 MP to reinforce the extra model.
They are at best equal to Riflemen with 1 BAR, but usually narrowly lose as far as I could tell in tests. While costing the same basically (270MP/60MU vs 280MP/60MU) and Riflemen can get the edge with a second BAR.
