What is the first step in applying remedial action with the M16/A2?

The first step in applying remedial action with the M16/A2 is to place the weapon on safe. This action ensures that the firearm is in a safe condition before any further handling or troubleshooting is done. This step is crucial in maintaining safety for the individual and those around them, as it prevents any accidental discharge during the remedial action process.

Once the weapon is placed on safe, the soldier can then proceed to evaluate the situation, which may involve removing the magazine, locking the bolt to the rear, and observing for any visual issues. These subsequent steps are important but should only be taken after ensuring the firearm is in a safe state. This order of operations highlights the emphasis on safety in military weapons handling protocols.
