M1A1

The M1A1 Thompson, Tommy Gun or simply, the  as it is known in-game was introduced in the v0.6.5 "" update on November 9, 2018. It is an SMG that runs on .45 ACP.

Although the M1A1 replaces the MP5 in the Desert Map, the weapons are highly different from one another. It's only found in the desert map during the desert events, relatively common in the map.

Strategy
When using the M1A1, it is necessary to get close to the opponent due to its poor accuracy and slow bullets. At close range, an M1A1 user can take advantage of its decent DPS and magazine size. Be sure to ditch it for anything else by late game, as later game will be dominated by shotgun and assault rifle users.

If playing with teams, this is a very good weapon to rush other people with your friends dispite the fact that this weapon has ok damage.

Trivia

 * It's the fourth WW2-era American weapon, with the M1 Garand being the first, the BAR M1918 being the second, and the M1911 being released at the same update.
 * It's the first SMG to be added in the game to not use 9mm.
 * The M1A1 is the oldest SMG of its class, starting production in 1921, about 45 to 50 years before both the MP5 and MAC-10, both of which were put in production in 1966 and 1970 respectably.
 * This weapon served the US military from the 1920's to the early 1960's when it's phased out by it's lighter counterpart, the M3/M3A1 "Grease gun".
 * This is the WW2 M1 variant of the Thompson SMG, as it lacks the iconic drum magazine compatibility, finned barrel, and the top charging handle of the weapon, which heavily contrasted from the iconic M1928 models.
 * Because that time the 30 rounds box magazine were popular and despite carrying 50 rounds drum magazine were difficult for US military,so they decide to use M1 SMG,and later M1A1.
 * The reload sound for the M1A1 depicts it as having to be cocked after reloading. Cocking an M1A1 using box magazines isn’t necessary as the magazine has a built-in bolt-hold-open device that locks the bolt to the rear when it is empty. As an open-bolt weapon, no further working of the bolt is required of the Thompson, and in theory, it would be always ready to fire regardless of whether or not the previous magazine was empty.
 * The sprite for the M1A1 correctly has a 30-round magazine.
 * If lieutenant grab M1A1, it will have 50 rounds, more akin to the common potrayal of the thompson, though having this ammo capacity makes no sense for the M1 Thompson due to the inability to mount drum magazines.
