Background and objective: To ensure effective carrying, scouting, patrolling, and large-scale combat operations, the workspace design of light armored vehicles (LAVs) should be compatible with anthropometry and range of motion (ROM) measurements of the soldiers. This study examines the extent of mismatch between the anthropometric dimensions of the Ethiopian army and existing workspace dimensions of the LAV. Predictive equations have been formulated for design dimensions considering anthropometry and ROM of the target population to avoid possible incompatibility. Method: The assessment was conducted on three existing Ethiopian LAVs, and mathematical equations were framed to predict the vehicular design dimensions. Anthropometric and ROM data of Ethiopian soldiers (n = 310) from an earlier reported survey by the authors were utilized. The accommodation capacity of existing LAVs was evaluated using a one-way or two-way (mis)match criterion, based on individual workspace characteristics. Along with the predicted dimensions, key vehicular dimensions were compared with other globally accepted vehicular standard dimensions. Results: Twenty-two basic design dimensions that comply with ergonomics principles were proposed. A high mismatch (in terms of the accommodating capacities of the three LAVs) between the existing and predicted design dimensions indicates the incompatibility of the existing design dimensions in their accommodation of most Ethiopian army personnel. The predicted dimensions comply with different global vehicular standards, thus validating the results. Conclusion: The research findings indicate that the incompatibilities between vehicular space dimensions and army personnel's anthropometry must be addressed to evade the adverse consequences on occupational health. The LAVs should be redesigned according to the anthropometry and ROM dimensions of Ethiopian soldiers. © 2021 Wiley Periodicals LLC
