We all go on about how good the old SLR rifle was, but remember just how heavy it was with a full mag and the bruise it would leave on your shoulder from the kick back.
But with a well-placed sliver of matchstick it could give a very quick double-tap with one trigger pull - excellent!
If you thought an SLR was heavy, try carrying a GPMG with ammunition for a couple of weeks - puts hairs on your chest, but keeps the natives' heads down!
Weapon of choice does have to be the
m203 grenade launcher mounted on an M16.
