The M4 carbine fires NATO standard 5.56x45mm ammunition. This is often confused with commercial .223 Remington ammo, which is dimensionally similar. However, they are not the same.

Not only the Army, but all the other service branches, as well as several law enforcement agencies (although theirs may have the government profile barrel, rather than the M4 profile barrel with the notch to accommodate the M203 or M320 grenade launcher). Not every Army unit uses the M4, or has it as the standard issue weapon - there are units in the Army where the M16 is standard, and the M4 may be reserved for support personnel, officers, etc.
