Analysis of the USAIS (US Army Infantry School) IMAAWS (Improved Medium Antiarmor Assault Weapon System) Portability Demonstration

摘要

The US Army Infantry School conducted a demonstration of the portability of the Improved Medium Antiarmor Assault Weapon System (IMAAWS), using mock-ups weighing 11, 16, and 20 kg (25, 35, and 45 lbs). The demonstration revealed no significant differences among the different loads in their effects on marching time, heart rate, blood pressure, time to fire a rifle or marksmanship. This report provides details which show that the lack of significant differences was caused by the ideal and unrealistic conditions under which the demonstration was held. USAHEL's conclusion remains that the IMAAWS should add less than 14 kg (30 lbs) to the soldier's load.
