The M1068 SICPS was a Cold War-era U.S. Army Command Post Vehicle born from the ubiquitous M113 Armored Personnel Carrier.

The M1068 SICPS (Standard Integrated Command Post System) became a further modification of the M577 Tactical Operations Center (TOC) vehicle which, itself, was born from the M113 Armored Personnel Carrier. The M577 included many changes to the base M113 model for the command post role such as a raised hull roof (25.25 inches), expanded communications suite, twin 60-gallon fuel tanks, a portable 28-volt generator, integrated cabin heater, folding table, and a 10-meter antenna mast. There was support for an optional, attachable tent system that could be erected at the rear of the vehicle for an expanded headquarters-type area. The vehicle lacked the commander's seat as well as his cupola.

The M577 was ordered into production even before the Army had received its first pilot vehicle. 270 M577 vehicles were produced by FMC Corporation from December of 1962 into May of 1963. Another 674 vehicles arrived from manufacture spanning November 1963 into 1964. Original gasoline-fueled production models were designated as M577. The switch to a diesel engine created the M577A1 designation during the 1960s. The M577A2 was nothing more than an M577 vehicle built upon the chassis of the new M113A2 APC. Older M577 vehicles were then upgraded to the new A2 standard. The M577A3 included the RISE powerpack with more powerful engine installation and larger, diesel-fueled generator unit.

In time, a new program brought two-thirds of the existing M577A2 fleet to the "M1068" standard to become the Standard Integrated Command Post System (SICPS) carrying the Army Tactical Command and Control System (ATCCS). The model included a 5kW diesel-fueled generator and all-new illuminated tactical tent design. The inclusion of the RISE powerpack to M1068 models produced the M1068A3 designation.

As these vehicles were based on the M113, their running gear and general appearance was similar and, thus, so were performance specifications. The crew typically numbered four. A large powered rectangular door (with smaller, inset hinged door) served the rear quarters of the vehicle. The auxiliary generator was fitted over the front-end of the hull.
