@Shotrocket6: Standard loadout is an M16A4 and 180 rounds for anyone not packing a SAW. SAW gunners usually carry about 600 rounds, with their A-gunner packing extra ammunition. Fire team leaders or other Marines with M203s usually carry a half-dozen 40mm grenades. That's the MINIMUM combat load for anyone stepping off on an op. But then you get smart and carry as much ammunition as you can, leverage additional weapon issues, cut crack deals with armorers, liberate equipment, take battlefield pickups, and miser as much firepower as you can get.
