I don't now but it feels like crew go hmg42 is more survivable.
DPS between factions is balanced for the squad sizes, so the PFs are one of the toughest squads in the game save for Shocks and the 4-man Allied squads are basically made of glass.
Of course there are other factors in the equation such as cost and specific-range effectiveness to determine their true values, but nonetheless it should be the case that against bullets in general, a 4-man Axis squad is as survivable as a 6-man Allied squad.
And then squad bunching made 4-man Axis squads get wiped by the things that aren't bullets all the time anyway.
