M1 Carbine

The M1A1 Carbine was a semi-automatic rifle featured in Call of Duty, Call of Duty: United Offensive, Call of Duty 2, Call of Duty 2: Big Red One and Call of Duty: World at War.

Call of Duty and United Offensive
In Call of Duty, the Carbine, (the paratrooper model known as the 'M1A1'), is a good alternative to the Garand. It has a magazine capacity of 15 rounds. Although chambered in the .30 Carbine round, which has the power and penetration of a pistol round, the rounded shape of the bullet expands on contact, causing high damage to enemies. Unlike the Garand, the game allows you to reload the Carbine at anytime. The recoil is minimal, so players will not have to readjust every time they fire. Like the Garand, it can be used in close-quarters, but won't always guarantee a victory. It is more effective at medium range but is still accurate at longer ranges.

In United Offensive, it does slightly more damage than its Call of Duty counterpart.

Call of Duty 2
The Call of Duty 2 M1 Carbine is a little different from the Call of Duty version. This model is the standard M1, and not the M1A1 used by the Army Paratroopers. It also has earlier model rear sights. It has moderate recoil, making it harder to use without having to readjust every time it is fired. It does good damage; with three or four shots to the body or one shot to the head needed for a kill. It has larger ironsights, making it a little harder to accurately hit a target than the earlier version. However, it's still a great alternative to the Garand. As one of the main characters is a part of a Ranger Battalion, the game designers' choice of using the standard M1 model issued to infantry and Rangers over the previously used M1A1 paratrooper model is historically accurate.

Call of Duty 2: Big Red One
In Call of Duty 2: Big Red One the Carbine is the M1 model, not the M1A1, and is first seen as being used by Pvt. Roger in "Piano Lupo", but becomes the standard issue in the game by "The Last Train".

Singleplayer
It can be found during the American campaign, though it is quite rare. It can be most easily found late in the game during Blowtorch & Corkscrew and Breaking Point, where many allied riflemen wield one, as the M1 Garand is still common though. One soldier can be found wielding one at the beginning of Burn 'em Out, if you kill him, you can pick the Carbine up, as it would come in handy for the Japanese MG in the bunker.

Multiplayer
The M1 Carbine is an excellent weapon for its high accuracy and high damage with a high magazine capacity as well. The biggest flaw, however, is that the weapon is only accessible on Level 65 or on Level 1 if the player pre-ordered the game, but the class will be replaced by a 6th Custom Class slot if the player prestiges. This weapon is not very popular because it is unlocked at level 65, and since most players prestige at this level, they will lose the carbine. Also, the weapon's iron sights are regarded as inferior to other rifles' by most players, and it is the only gun that does not provide clearance for the bottom half of the Aperture Sight, as the bottom half of the sight is almost completely blocked by the weapon. The reload is also just a tad longer than most weapons, however because of the extra rounds in the magazine reloading isn't as much of a problem. It it also seen commonly in conjunction with the tier 1 perk M2 flamethrower, most likely because they are both unlocked at level 65, and because they work well together.

Its accuracy and damage are equal to the Gewehr 43 and SVT-40, and coupled with a large magazine capacity, it allows the user to take down multiple targets with single magazine. Because of this, the Carbine is often used by players with modified controllers. The Box Magazine attachment increases the magazine size to 30 rounds, much larger than the SVT-40 and Gewehr 43. The 1st Perk slot Bandolier gives the carbine a large ammunition reserve which is often not needed. In close quarters environments, the Carbine is a good option for players who like to use rifles in close quarters.

Due to the weapon's high accuracy and damage, it is possibly one of the better guns to use in a stealth class with Camouflage, Dead Silence, and a Flash Hider equipped, allowing the player to find a quiet spot, easily pick off a few enemies, and then move along to another location without too much trouble. This gun is a good choice for hardcore, as it can pull-off one-shot kills even without Stopping Power.

The M1A1 also has a very raspy and unique firing sound, so attentive players will know when someone on the enemy team is using the gun.

Nazi Zombies
The M1A1 Carbine is available on all Nazi Zombie levels. Like all semi-automatics, it loses its effectiveness after the first seven rounds.

If you upgrade the M1 carbine in the Pack-a-Punch Machine machine in the zombie map "Der Riese", the M1 carbine will become fully automatic, (similar to the M2 variant) and its name becomes the "Widdershins RC-1". The word "Widdershins" is a Germanic word which means "in a direction opposite to the usual". Some players think that upgrading the weapon is a waste of 5000 points. Hence the name.
