Here are some new Army publications regarding range ops available from Army Publications Directorate:
TC 25-8, 11/2/2021, Training Ranges
ATP 5-19, 11/9/2021, Risk Management
ATP 4-35.1, 11/8/2021, Ammunition and Explosives Handler Safety Techniques
Does change this have to do with the recent News article about lost C-4 and 40 MM grenades?
