The Canadian Forces are actively engaged in operations overseas and are in need of a new modular fighting rig (MFR) to meet the demands of the current operational requirements in theatre. The aim of this pilot trial was to provide a preliminary assessment of each of the Modular Fighting Rig (MFR) candidates for usability, acceptability to soldiers, and compatibility with a range of soldier equipment and tasks, as well as, a preliminary assessment and characterization of the preferred placement of soldier load items. This pilot trial was also used to evaluate and develop methods to evaluate the modular fighting rig in future evaluations. In conjunction with a Soldier Integrated Helmet System (SIHS) trial, a 10 day fit and evaluation trial was conducted at Canadian Forces Bases (CFB) Valcartier from September 28 to October 9, 2009. Fourteen soldiers were required to undertake a battery of human factors tests while wearing one of the MFR systems in a repeated measures design. Human factors tests included assessments of fit, comfort, range of motion, performance of select battle tasks, and equipment, vehicle, weapons, and clothing compatibility. Data collection included anthropometric measurements, range of motion measurements, questionnaires, focus groups, live fire performance measures, and Human Factors (HF) observer assessments. Overall, the participants preferred MFR A1 as the most acceptable vest. Participants noted that all of the features of A1 were acceptable for combat
