Are you sure? Pull the mag, cycle the bolt to extract, close the bolt. Engage the safety. Insert the full mag.
I think it is just plain stupid. It's a war zone. Any delay between detecting a threat and reacting raises the prospect of being killed while having to cycle the bolt again and move the safety to "fire". It's the same stupid logic that demands storing a home self defense weapon unloaded and locked away separate from the ammo.
Which would leave the weapon cocked with an empty chamber, just like I said.
