Being the standard-issue weapon of the US Army Rangers, this is the first gun Nathan Hale gets in Resistance Fall of Man. This gun also features a M200 40mm grenade launcher utilized by pressing the L1 trigger which can be used in quick reaction situations to dispatch numerous Chimera.
The M5A2 Carbine is often referred to as "the paddle" due to the large stock which can be used to beat upon Chimera heads. This is known as "spanking" the enemy. 
The M5A2 rifle is chambered for .303 rounds, the same as the British Rifle.
