Final protective fire

 

The term "final protective fire" means the highest priority is given to this request due to the danger of a position being overrun. For the guy in the trenches, that means firing as fast as possible to break up a determined assault - even if that uses up barrels and ammo fast. If the FPF fails, there won't be a "later" for those troops.
 
How does this relate to civilian self-defense? Very directly: almost every defense against a foe with a contact weapon is an FPF event. Most short range shootings are the same. They are rapid affairs with very little care given to the aftermath - if you fail to stop a guy with a shank, there won't be an "after" for you. The difference is that you seldom have another person covering you and have to rely on your own firepower to break the attack.
