What is the initial step in loading the M240?

The initial step in loading the M240 involves opening the feed tray cover and inserting the ammunition belt. This step is crucial because the feed tray is specifically designed to hold the ammunition and allows for the proper feeding mechanism to function effectively. By opening the feed tray cover first, the operator prepares the machine gun to accept the ammunition belt without obstructing the feed mechanism. This ensures that there are no issues when the weapon is cycled after loading. Once the belt is securely in place, subsequent steps can be taken to fully prepare the weapon for firing.

Each choice reflects elements involved in the M240 operation, but opening the feed tray cover and inserting the ammunition belt is a fundamental step that lays the groundwork for the entire loading and operational process.
