The M58 Mine Clearing Line Charge (MICLIC) is a rocket projected explosive line charge which provides a "close-in" breaching[disambiguation needed] capability for maneuver forces of the United States Army and Marine Corps. It is effective against conventionally fuzedland mines and, when detonated, it provides a lane 8 meters by 100 meters. The MICLIC system consists of an M353 3½ ton or M200A1 2½ ton trailer (or M200 tracked trailer) chassis, a launcher assembly, an M147 firing kit, an M58A3 line charge and a 5-inch MK22 Mod 4 rocket. The line charge is 350 feet long and contains 5 pounds per linear foot of C-4 explosive. In the event a MICLIC fails to detonate normally, it can be manually activated by time-delay fuses every few feet along the length of it. Due to the inherent dangers of entering a live minefield to manually arm the backup fuses on a charge that could still detonate at any moment, possibly while under enemy fire as well, the act is jokingly referred to as the "Medal of Honor run".
