Abstract

Aim: To compare experts and novice law enforcement officers in defensive skill execution, using the Defensive Tactics and Arrest Control (DETAC) gauntlet. Design: A retrospective cohort study. Method: Data for 15 police DEFTAC instructors (age = 31.93 ± 6.98yrs; height = 194.02 ± 17.03cm; mass = 87.55 ± 12.25kg) and 36 general duties officers (age= 39.67 ± 8.32yrs; height = 186.40 ± 14.59cm; mass = 89.62 ± 13.90kg) completed DEFTAC training. Four DEFTAC subject matter experts evaluated police officers’ ability to execute the techniques as trained, and their physical ability to perform each defensive skill. Defensive skills included edged weapon disarm (EWD), holstered gun retention (HGR), blunt object defence (BOD), gun disarm (GD) and prone handcuffing (PH). Results: Instructors outperformed (p<.001) general officers in ‘techniques-as-trained’ in all five techniques and in ‘physical-ability-to-perform’ for EWD (p<.001), HGR (p<.001) and GD(p<.05). Conclusion: Police training and physical assault are leading cause of police officer injuries. Police officers with higher levels of skill can perform DEFTAC skills more effectively and typically more physically efficiently, thus reducing their risk for movement error, and injury to themselves, other officers undergoing training and offenders.
