The Type 100 was a Japanese submachine gun designed in 1940 by Nambu Arms Manufacturing Company. It was first issued to the Imperial Japanese Army in 1940, usually only to officers, and its production continued to the end of the war. It used the 8x22mm Nambu cartridge in a 30-round magazine. Early models had a rate of fire of 450 rounds per minute, however, the 1944 models had a rate of fire of ~800 rounds per minute. It was heavily based on the Bergmann Mp18, and used a chrome body for resistance against humidity, giving it a sleek, silver-like finish.
It is a fully automatic weapon capable of efficiency in close quarters, but it's performance deteriorates at longer ranges since the player cannot aim down sights. It is capable of killing an enemy within around 7 to 10 body shots, though its mediocre accuracy will require a few more shots to finally kill an enemy.
Battlefield: Bad Company 2
Only available in singleplayer, the Type 100 in Battlefield: Bad Company 2 makes a brief appearance in the opening mission, Operation Aurora. It is the first gun the player uses. It is not included in multiplayer. It is one of the two usable infantry weapons during Operation Aurora and one of the two weapons available in singleplayer that is not a collectible weapon.
It has a high rate of fire and effective damage, as well as generally clear iron sights. It has medium recoil and it is slightly ineffective at long ranges because of its mediocre accuracy.
- In Battlefield: Bad Company 2, during the final cutscene of Operation Aurora, the Type 100 in Thomas Wyatt's hands does not have a magazine inserted, but actually has the magazine stuck under the gun itself.
