TM 10-1670-287-23&P  0002 00  MC-4 RAM AIR FREE-FALL PERSONNEL PARACHUTE SYSTEM  EQUIPMENT DESCRIPTION AND DATA  EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES  A summary of the characteristics, capabilities and features of the equipment is contained in the following  subparagraphs: The MC-4 Ram Air Free-Fall Personnel Parachute System (front and back view) is designed to place  Army personnel into areas of mission interest. An MC-4’s inherent gliding capability offers important  potential for minimizing detection during entry or changing the landing area during descent in order to  avoid capture. The high altitude standoff capability significantly reduces aircraft vulnerability and  detection. The various modes of the MC-4 parachute use, such as High Altitude High Opening (HAHO) and High  Altitude Low Opening (HALO), provide versatility and opportunity for controlling descent which are not  possible with standard (round) or less efficient gliding parachute designs. 0002 00-1  Change 1
