What is the first step personnel must perform on the command LOAD?

The first step personnel must perform on the command LOAD is to ensure the pistol is in Condition 4. This refers to the status of the firearm, where the chamber is empty and there is no magazine inserted. Ensuring the pistol is in this condition is crucial for safety before beginning the loading process, as it allows personnel to handle the weapon without the risk of it discharging inadvertently. It sets the stage for a controlled and safe procedure, as the weapon is in the least ready state at this point.

Once the condition of the pistol is verified, personnel can proceed with loading the magazine, chambering a round, and other actions necessary for preparing the firearm for use. Properly following this sequence helps maintain safety protocols that govern the handling of firearms.
