What is a hogs tooth?

Answer 1

its a necklace which has a thread put through a hole drilled in round taken from a 7.62*51mm NATO cartridge (standard round for most us marine sniper rifles) (commercially a .308 winchester).

its presented to us marines snipers on graduation from scout sniper school, thus becoming a HOG (hunter of gunmen).

the philosophy is that there is a round meant for you and the hogs tooth represents that round and by wearing that necklace, the sniper assures himself that he has control over the round that is meant for him.

the necklace (hogs tooth) actually represents the round which is in the chamber of the enemy's gun zeroing in at the sniper and right before the enemy could fire, the sniper fires and takes the enemy out. after that, if possible (given the battle scenario), the sniper would go down range, get hold of that enemy's rifle and eject that round which the enemy was about to fire, and then keep that round as a symbol that he has control over the round which is meant for him. (probably the round that has been recovered from the enemy's rifle is HOG's TOOTH in true sense of the phrase).

i hope i have been to put it as clearly as i know it.
