Abstract: The project was initiated at the request of two platoons of Combat Engineers, military occupational specialty 21B, who serve as part of the Kansas National Guard. The U.S. Army Research Laboratorys (ARLs) Human Research and Engineering Directorate performed an evaluation of the emergency egress characteristics of the Buffalo. ARL developed a plan to evaluate the emergency egress characteristics of the Buffalo using human figure modeling. A detailed analysis of the vehicle roof hatch was performed to identify whether the larger end of the male Soldier population, with equipment and clothing, could fit through the hatch. The results of the egress modeling identified some shortcomings with the emergency egress characteristics of the Buffalo and two recommendations were made: (1) increase the hatch size to 69 cm by 50 cm or (2) use a circular hatch with a diameter measuring 61 cm instead of a rectangular or square hatch. The results and recommendations from the modeling were used to help drive design modifications that, if implemented, could enhance the emergency egress characteristics of the Buffalo.
