Notes: Originally a joint design between Daewoo and the American company of Atchisson, the USAS-12 was classified as a Class III destructive device in the US and Atchisson dropped out of the partnership, feeling there would be little or no US sales. The original design was the Daewoo/Atchisson AA-12 Assault Shotgun, a selective fire shotgun designed to fire standard as well as exotic ammunition. This was later modified by Daewoo in the hopes of US sales and renamed the USAS-12, but the large ammunition capacity of the magazines dashed hopes of this too. Both weapons can be fed by large capacity box or drum magazines. The weapon is designed like an assault rifle, and bears a superficial resemblance to the M-16. The low rate of fire helps keep recoil low, especially during automatic fire.

This weapon has recently been issued to US troops in Afghanistan and Iraq on a test basis for use in close assault situations.  The troops using them tend to like the incredible firepower, but not the rather beastly weight.

Twilight 2000 Notes: The USAS-12 received a surprising amount of use during the Twilight War, not only by the South Koreans, but by US, British, Australian, and Mexican troops. They were used mostly by special operations units and by military police.

Merc 2000 Notes: These weapons were favorites of gangs on the US West Coast, and were also used by police and military special operations units.
