What is the first step in addressing a cold gun failure?

In the context of addressing a cold gun failure, the first step is to ensure safety by locking the bolt and placing the weapon on the SAFE position. This action is crucial because it secures the firearm, preventing any accidental discharge while troubleshooting the issue. By locking the bolt, the operator ensures that the mechanism is inactive and cannot fire, which is a fundamental safety protocol when dealing with any firearm malfunction.

Following this safety measure, the operator can then assess the situation more effectively, whether that involves checking the ammunition, inspecting malfunctions, or determining if support personnel need to be called in. It establishes a control step that allows the crew to proceed safely and confidently with subsequent troubleshooting steps without immediate risk.

The other options, while potentially relevant to the troubleshooting process, do not prioritize safety to the same extent as securing the firearm before addressing any issues.
