Ever shoot someone with an M4 only to be killed by their SCAR-L with less ammunition?
In reality both of these firearms utilize the 5.56 x 45mm ammunition, so that would lead one to conclude that they should do the same amount of damage. Another weapon that is horribly under powered is the M95. The M95 fires the .50 BMG (12.7 x 99mm) which in reality kills with just a single round, even with body armor. (I have friends whom have served in Iraq who can confirm this, if for some reason you doubt my words. The marines use the M82A1 Semi-automatic .50 BMG) The .50 BMG can even take down Helicopters with a single round to the engine block.
