Abstract:

This research note describes the MANPRINT assessment which forms part of the Follow-On Evaluation FOE of the M1A1 main battle tank conducted at Fort Bliss from December 1986 through August 1987 by the Army Operational Test and Evaluation Agency. MANPRINT evaluation support was provided by the Army Research Institutes Fort Hood Field Unit. The M1A1 FOE was conducted using 41 of the tanks assigned to the 3rd Squadron, 3rd Armored Cavalry, and their crews. Data for the assessment were obtained through structured interviews, questionnaires, observation of squadron operations and evaluation of calibrationgunnery performance of crews during the FOE. The primary issues investigated were ease of calibration of M1A1 main armament, logistic supportability, and NBC system operations. Inquiry was also made as to the number of previously identified MANPRINThuman factors deficiencies uncorrected in the production version. Significant findings during the FOE were insufficient refueling capacity in the tested support platoon, low reliability of the Simplified Test Equipment, when used in high ambient temperature conditions, and an NBC backup system which does not filter out carbon monoxide gas a deficiency discovered during the M1E1 operational test II in 1984.
