wtf are you smoking? The only infantry that can win against them are mandos.
90% of brits are commandos, and they eat your 160 mun grens for breakfast and shit out grenades.
Against rangers they pwn, but one LMG gren can fight rangers reasonably well as well, you dont need dual LMGs.
meh, yeah, they´re a bit useless against brits, but 1 LMG vs 1 SMG squad is even.. the 2nd LMG makes you win the fight like 90% of times.
