if you go the the armory part b4 the mission starts, if some1 has a lock for his grenade or satchel.. select 'fire team' and put ur 'chooser' at the locked thing, switch a few times untill u get the 2x ammo

if im correct the teammates without an lock will have now double double ammo!

i discovered it at the last lvl(if russia is the last!)
and there it only gives ur teammates extra double ammo.

and i just wanna say this: that russian guys rulz! especially their dialect =P
