Abstract : Ten representatives of the Institute of Human Performance were integrated into a marine battalion during a high altitude cold weather training operation for the purpose of gathering descriptive and objective information about the types of physical performance tasks encountered by marine infantryment (MOS 0311). Through the use of minicassette recorders, scales, cameras and other data collection equipment, scenarios were described which typify the critical, frequent and strenuous types of tasks indigenous to marines in this environment. Distances covered on foot, loads carried, rates of travel and grades encountered were detailed and described, as well as other environmental overlays which impact on troop performance. Sustained marches, under varified atmospheric conditions, weighted with awkward personal protective equipment approaching 70% of one's body weight, was identified as the overriding physical task in this environment. Unpacked snow, and grades of 10-15 were routinely encountered. An ability to maintain a line of march for periods of four to six hours were not uncommon. The arduous nature of this task was confounded by frequent falling into deep snow while wearing snow shoes and having to reestablish an upright position.
