The M1 Carbine, formerly designated as the United States Carbine, Caliber .30, M1, is a lightweight carbine chambered for the .30 Carbine round.
The M1 carbine served as a lighter and more compact alternative to the unrelated M1 Garand, and was typically issued to airborne infantry, vehicle crewmen, and rear line elements. It filled a role similar to today's personal defense weapons, offering greater firepower and range over the standard sidearms like the M1911, M1A1 Thompson, or M3 grease gun, but a larger magazine and better portability than the M1 Garand. However, subpar firepower eventually lead to its replacement after the Korean War by the M14, though it continued to serve in some applications until at least the Vietnam War.
Still in use by some military and police forces around the world today, the M1 Carbine lacked the stopping power of the M1 Garand but was popular because of its ease of use and weight. The M1A1 variant is a Paratrooper model of the M1 with a folding stock and pistol grip.
The M1 is an all kit Carbine introduced alongside the Battlefield Hardline: Robbery expansion. Like the M1A1, which was released alongside the Criminal Activity expansion, the M1 does not require ownership of the expansion and is available to all players.
The M1 has less range than most of the other Carbines and Assault Rifles and is also only semi-automatic, but has high damage, making it a good mid-ranged weapon. Similar to the M1A1, the M1 Carbine is only able to equip weapon specific attachments and can only equip Metallic Paint. The M1 is able to equip a Stock, Stubby Grip, and Flash Hider.
Upon obtaining the first gold service star for the M1 Carbine, the "Grandpa's Automatic" achievement/trophy will be unlocked.
