I was told a long time ago that under every US flag on any military installation is a pin. You pull that pin and the flag falls over pointing North. Under that flag is a straight razor, a box of "strike anywhere" matches and an M1911 .45 cal pistol with one bullet.
This is called "Last man standing" The last man alive on post is to do this.
You fall the flag, retrieve it before it hits the ground, take it back to the base, cut out the stars and burn the stripes, Fold the stars and put it against your chest… Shoot yourself with the .45.
