12g Automatic

The Browning Auto 5 is an American 12-, 16-, or 20-gauge semi-automatic shotgun designed by John Browning in 1898. It was the first succesful, mass-produced semi-automatic shotgun ever. It used a 4-round tubular magazine feed system, and can have a maximum capacity of 5 rounds with an extra round in the chamber. It was, and still is, widely used by law enforcement, military and civilian groups.

Battlefield 1942: Secret Weapons of WWII
In Battlefield 1942: Secret Weapons of WWII, the Browning Auto-5 (simply named Shotgun in-game) is issued to the SAS Engineer kit. It features low recoil, a moderate rate of fire, short range and high damage. It uses a 5-round magazine with [?] magazines reserve. It is the ultimate close quarters weapon, as it has very high damage in close quarters, as well as poor accuracy, ideal for shorter ranges. It can easily kill in a single shot, though anywhere beyond 10 or so meters, the damage will drop rapidly and will not affect anywhere beyond 20 meters. It can usually be matched by a submachine gun, though a skilled player can usually best anything with the shotgun.

As the Engineer kit usually uses an unscoped bolt-action rifle, the shotgun can be an interesting change of pace for players, as it will usually force them to stay near tight urban areas, rather than in the open.
