The negative effects of overloading the soldier, such as fatigue, heat stress, injury, and performance degradation are under constant scrutiny as the soldier’s load is constantly modified and re-evaluated for the demands of the modern battlefield. Collectively, weight, bulk, and stiffness, as they pertain to the effectiveness and performance of a dismounted infantry soldier, may be termed soldier burden. The Canadian Load Effects Assessment Program (CAN-LEAP) was created in order to determine the implications of soldier burden on soldier mobility and combat tasks and to inform future soldier equipment design, testing and evaluation, as well as inform further research into the characterization of, contributors to, and strategies to mitigate soldier burden. For this CAN-LEAP experiment, the performance of dismounted infantry soldiers was characterized for a range of combat movements and tasks, and the effect of varying loads on soldier combat performance was examined. Twenty-eight regular Force combat arms personnel volunteers participated in two weeks of data collection. Each week a new set of participants completed the CAN-LEAP course in seven different load conditions, presented in a repeated measures counter-balanced design. The seven conditions represented the typical load configurations borne by a range of infantry or combat arms soldier roles (e.g., Dismounted Rifle Section Commander, Grenadier, Light Machine Gunner, C7 or C8 Rifleman), as well as alternative concepts
