The M1126 infantry carrier vehicle (ICV) is an armored personnel carrier and part of the Stryker family of vehicles (derived from the Canadian LAV III/Swiss MOWAG Piranha IIIH 8x8) used by the United States Army and Royal Thai Army.

[citation needed] The basic infantry carrier vehicle (ICV) provides armored protection for the two-man crew and a squad of nine soldiers.

Army officials plan to up-gun Stryker ICVs with a 30 mm cannon in a Kongsberg Protech Systems' Medium Caliber Remote Weapons Station (MCRWS),[2] which does not extend into the crew compartment and take up space and can be loaded from inside.

[4] After comparative testing of the Kongsberg MCRWS mounted to Strykers, the U.S. Army approved on 22 April 2015 the equipping of 81 of the 2nd Cavalry Regiment's Strykers with 30 mm Mk44 Bushmaster II cannons following a lethality upgrade request to increase lethality against other light armor vehicles while preserving its wheeled mobility advantages.

[8] In April 2019, the Army decided to add cannon armament to three additional brigades of Stryker DVH ICVVA1 vehicles.
