Abstrakt: Challenges for some women meeting the physical employment standards (PES) for ground close combat (GCC) roles stem from physical fitness and anthropometric characteristics. The purpose of this study was to identify the modifiable and nonmodifiable characteristics predictive of passing GCC‐based PES tasks and determine the modifiable characteristics suitable to overcome nonmodifiable limitations. 107 adults (46 women) underwent multiday testing assessing regional and total lean mass (LM), percent body fat (BF%), aerobic capacity (V̇O2peak), strength, power, and PES performance. Predictors with p‐value <0.200 were included in stepwise logistic regression analysis or binary logistic regression when outcomes among sexes were insufficient. Relative and absolute arm LM (OR: 4.617–8.522, p < 0.05), leg LM (OR: 2.463, p < 0.05), and upper body power (OR: 2.061, p < 0.05) predicted medicine ball chest throw success. Relative and absolute arm LM (OR: 3.734–11.694, p < 0.05), absolute trunk LM (OR: 2.576, p < 0.05), and leg LM (OR: 2.088, p < 0.05) predicted casualty drag success. Upper body power (OR: 3.910, p < 0.05), absolute trunk LM (OR: 2.387, p < 0.05), leg LM (OR: 2.290, p < 0.05), and total LM (OR: 1.830, p < 0.05) predicted maximum single lift success. Relative and absolute arm LM (OR: 3.488–7.377, p < 0.05), leg LM (OR: 1.965, p < 0.05), and upper body power (OR: 1.957, p < 0.05) predicted water can carry success. %BF (OR: 0.814, p = 0.007), V̇O2peak (OR: 1.160, p = 0.031), and lower body strength (OR: 1.059, p < 0.001) predicted repeated lift and carry success. V̇O2peak (OR: 1.540, p < 0.001) predicted 2‐km ruck march success. Modifiable characteristics were the strongest predictors for GCC‐based PES task success to warrant their improvement for enhancing PES performance for women. Highlights: Women in GCC roles require sufficient military‐specific physical fitness and anthropometric parameters, independent of sex, for successfully passing GCC‐based PES tasks as part of assessment testing and selection procedures for GCC roles.Passing GCC‐based PES tasks involving heavy lifting, dragging, pushing/throwing, and carrying may benefit from increased upper body (arm and trunk) and lower body lean mass and upper body power and maximal strength, whereas passing material handling tasks may benefit from lower percent body fat, greater lower body muscular strength, and higher aerobic capacity with the latter important for passing load carriage tasks.Military trainers should target modifiable characteristics, including upper body lean mass, power, and maximal strength to improve GCC‐based PES task performance in women.
