What should a guard NOT use a firearm for?

The appropriate use of a firearm by a guard is strictly regulated and limited to specific circumstances, usually pertaining to self-defense or the protection of others from imminent harm. A firearm should not be used as a means to intimidate or frighten individuals, as this can escalate situations unnecessarily and lead to dangerous outcomes.

Using a firearm as an offensive weapon goes against the principles of responsible firearm use and can result in severe legal consequences, putting the guard and others in peril. Likewise, employing a firearm to warn others is not a recommended practice; there are more appropriate ways to alert individuals to danger without resorting to a weapon.

In summary, the correct answer encompasses all these inappropriate uses, highlighting that a guard should refrain from using a firearm in any of these contexts, ensuring adherence to safety protocols and legal standards.
