During a tactical operation, is it true that you must turn off the engine before refueling?

Turning off the engine before refueling is essential for maintaining safety during tactical operations. An operational vehicle produces heat and emits fuel vapors, which can increase the risk of fire or explosion when it comes into contact with fuel fumes. By turning off the engine, you eliminate a potential ignition source, thereby reducing the risk of accidents during the refueling process.

In military operations where safety and operational security are paramount, following this precaution helps ensure that personnel and equipment remain safe from avoidable hazards. Adhering to proper refueling procedures, including the engine shutdown, aligns with best practices and standard operating procedures within military guidelines.
