The M142 High Mobility Artillery Rocket System (HIMARS) is a light multiple rocket launcher developed in the late 1990s for the United States Army and mounted on a standard U.S. Army Family of Medium Tactical Vehicles (FMTV) M1140 truck frame.

With its precise fire power, enhanced responsiveness and mobility, the HIMARS has been operated by 23rd Battalion, Singapore Artillery (23 SA) during its training, both locally as well as overseas. The first live-firing by HIMARS was completed in an overseas exercise – Exercise Forging Sabre – in 2009.
