Safety, Safety, and More Damn Safety
You are to treat EVERY weapon that you touch, as if it is loaded. If it is your weapon, and it has been out of your control for any time (like at the #armory – under another's guard) you must still perform a chamber check to ensure that there is no round in the tube.
Even if the weapon is unloaded – you will not put your finger on the trigger. The #USMC Smokey Bear hat D.I. 's will bring down such #pain on you for forgetting TRIGGER AWARENESS; that you will forever be cured of the 'itch'.
The M-16 is a #tool meant for one thing – killing. You need to be trained in the proper safety and maintenance of the #weapon. At all times – except when actually engaging the enemy – your finger will be OFF of the trigger.
There are four stages to Weapon #Safety and Carry. You will be required to memorize them; and know them from rote.
