MOS 0341 Gunners Practice Exam

In mortar use, the most important safety consideration is keeping all personnel out of the firing zone because of the backblast and high-velocity fragments that can travel behind and around the tube. The mortar system can throw debris, causing injury or death if someone is too close, even if the round lands far away. Establishing and enforcing a safe distance around the mortar ensures everyone is outside the danger area before firing and during any misfire or malfunction. Weather or whether it’s day or night doesn’t change that hazard—the backblast and fragmentation remain threats, even if visibility is reduced. The way the controls are operated or whether firing happens at night doesn’t address the primary risk, which is staying clear of the danger zone.
