SRAM = Super Rapid Advanced Mortar System.
ST Kinetic''s 120mm SRAMS is the first mortar in the world with a
recoil force of less than 20 tonnes when firing maximum charge. The
system, weighing only 1200 kg, can be integrated into, and in some
cases, fired from onboard a wide range of light tracked or wheeled
vehicles.
