摘要

The purpose of this study was to assess the effects of gender, rifle stocklength, and weapon weight upon marksmanship performance and arm-hand steadiness. Thirteen female and fifteen male soldiers were recruited. Performance on the Noptel marksmanship simulator showed no gender differences in marksmanship with the M16A2 rifle (standard) and the M4 carbine (a lighter rifle). Reducing the stock length from 10.3 to 7.0 significantly improved marksmanship scores for both male and female soldiers. Weapon weight was a critical factor; shot group tightness was better with the lighter M4 carbine (6.9 lbs) versus the heavier M16A2 rifle (8.4 lbs). Similar findings were found with arm-hand steadiness measures: shorter and lighter weapon configurations permitted better steadiness regardless of gender. Overall stock length and weapon weight should be considered in any new combat weapon design.
