The Food Packet, Long Range Patrol or "LRP ration" (pronounced "Lurp") was a U.S. Army freeze-dried dehydrated field ration. It was developed in 1964 during the Vietnam War (1959-75) for use by Special Operations troops—small, heavily armed long-range reconnaissance teams that patrolled deep in enemy-held territory, where bulky canned MCI rations (formerly known as C rations) proved too heavy for extended missions on foot.
