M58 Mine Clearing Line Charge (MICLIC)

The Mine Clearing Line Charge (MICLIC) provides an effective minefield breaching capability for maneuver forces. The system consists of an M353 3-1/2 ton or M200A1 2-1/2 ton trailer (or M200 tracked trailer) chassis, a launcher assembly, M147 firing kit 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 composition C-4 explosive. Engineer units employ the MICLIC in response to minefield breaching requirements identified by the maneuver forces. The MICLIC's trailers are then towed to the selected area where an engineer prepares the line for firing. Once it is detonated, it clears a lane measuring 8 meters by 100 meters.

The MICLIC is a rocket projected explosive line charge which provides a "close-in" breaching capability for maneuver forces. It is effective against conventionally fused mines and, when detonated, it provides a lane 8 meters by 100 meters. The MICLIC system consists of an M353 3-1/2 ton or M200A1 2-1/2 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 composition C-4 explosive.

The US Army approved acquisition of the US Marine Corps' M58A3 Trailer Mounted Line Charge as a non-developmental item in Dec 83. MICLIC was type classified in Aug 85. Fielding to USAREUR occurred in FY88. Fielding to NG units continues.

Engineer units employ MICLIC in response to minefield breaching requirements identified by the maneuver unit. A typical mission is as follows: The Engineer Company's MICLIC trailers are moved to a position designated by the maneuver commander and the line charge prepared for firing by an Engineer squad. Suitable combat vehicles tow the MICLIC trailers to the point of the breach. Movement to the firing site and execution is done under control of the breaching force commander. A second MICLIC may be fired from the breached lane if a longer breach is required. After firing, the empty trailer is reloaded with another line charge brought forward from the supply trains, if additional breaching missions are anticipated. It may also be towed to a preselected position and dropped for later recovery by support elements.

BASIS OF ISSUE:

  • 6 per Engineer Company, Separate Heavy Brigade
  • 6 per Engineer Company, Armored Cavalry Regiment
  • 4 per Engineer Company, Heavy Division

  • 4 per Engineer Company, National Guard Division
  • 4 per Engineer Company, Corps (Mechanized Battalion)
  • 4 per Engineer Company, Corps (Wheeled Battalion)
  • 2 per Engineer Company, Separate Infantry Brigade
  • 2 per Engineer Company, Corps (Light Battalion)
  • 2 per Engineer Company, Corps (Airborne Battalion)
  • 2 per Engineer Company, Air Assault Division

TRAINING/PERSONNEL: Training for MICLIC is conducted through service schools, technical manuals, Training Extension Course tapes, Army Training and Evaluation Program and unit training. All combat arms officer and NCO courses include MICLIC employment considerations in obstacle breaching instruction. An inert M68A2 line charge is used for training. An improved MICLIC trainer is nearing completion. It will allow inert training on more installations due to a smaller range fan. A light trainer has been approved for garrison training.
