Abstract
The objective of this work was to assess the biomechanical performance of the current issue fragmentation vest, the Gen II 97-F with lap joint closure at both shoulders, the Gen IIIA with a side opening creating a continuous shoulder and the Gen IIIB with an asymmetrical one shoulder closure style. The dynamic behaviour of each design and its' impact on the user (asymmetrical loading, high hip reaction forces, and high contact pressures on the skin) was quantified using the Load Carriage Simulator. Designs were assessed for restriction to upper torso mobility using standard testing on the Load Carriage compliance tester. As well, the cause of any poor performance was reported. Finally, each fragmentation vest design was evaluated for compatibility with the proposed Tactical Assault Vest (TAV). Results and conclusions fell into two categories; factors related to user discomfort and factors related to user mobility.
