Shooting Stability: A Critical Component of Marksmanship Performance as Measured through Aim Path and Trigger Control

Abstract

Marksmanship proficiency is an essential component to operational effectiveness in the military. Previous research suggests marksmanship proficiency is dependent on shooter posture and weapon stability. This study evaluated new stability measures derived from simulator aiming data. Sixteen participants were assessed in three clothing and individual equipment (CIE) conditions involving traditional military ensembles. Marksmanship was assessed using traditional measures (precision and accuracy), as well as four new stability measures (horizontal, vertical, and overall stability, and trigger control). Significant differences in stability were seen across firing postures and fatigue states, consistent with previous study suggestions regarding the important role of stability on marksmanship proficiency. Regression analysis showed that horizontal stability and trigger control measures were also highly predictive of precision. Additionally, significant differences in all stability measures were seen across CIE conditions, suggesting that these measures provide valuable insights regarding CIE effects on marksmanship performance not fully captured by traditional marksmanship measures.
