The T250 is a Gatling-style 37mm rotary cannon with six barrels, used exclusively in the T249 Vigilante self-propelled anti-air system. While the SPAA itself did not generate that much interest (as it is really just another M113 with a massive gun Macgyvered onto it), the T250 did spur enormous curiosity between Oceanykan and Soviet engineers. When a T249 was captured and smuggled to the island nation, courtesy of the Viet Cong, they were ecstatic to witness such an enormous and awe-inspiring weapon. At a maximum rate of fire of 3,000 RPM, the T250 can empty its 192-round magazine in less than four seconds. An alternative fire mode of 120 RPM is available for ground support.
