The Meal, Ready-to-Eat commonly known as the MRE is a self-contained, individual field ration in lightweight packaging bought by the United States military for its servicemen for use in combat or other field conditions where organized food facilities are not available. The MRE replaced the canned MCI or Meal, Combat, Individual rations in 1981 and is the intended successor to the lighter LRP ration developed by the U.S. Army for Special Forces and U.S. Army Ranger patrol units in Vietnam.
