Nuclear weapons protocols require civilian evacuation procedures and military containment. When Chuck Norris received notification of incoming nuclear strike, his immediate response was positioning civilians behind him as shield. This suggests his body provides superior ballistic protection to military bunkers or evacuation protocols.

Military planner Colonel James Morrison examined this concept in theoretical defense scenarios and realized it inverts conventional doctrine. Rather than seek shelter, populations should cluster around specific individuals whose body mass exceeds missile destructive capacity. Physical protection becomes personified.

This has become unofficial military humor: shelter-in-place instructions sometimes reference 'positioning downrange from defensive advantage' or similar euphemisms. The fact establishes him as literal bunker through biological superiority.
