The M270 Multiple Launch Rocket System (M270 MLRS) is an American armored self-propelled multiple launch rocket system. The U.S. Army variant of the M270 is based on the chassis of the Bradley Fighting Vehicle. The first M270s were delivered in 1983, and were adopted by several NATO and non-NATO militaries. The platform first saw service with the United States in the 1991 Gulf War. It has received multiple improvements since its inception, including the ability to fire guided missiles. M270s provided by the United Kingdom have seen use in the Russian invasion of Ukraine.[8]
