Sniper 101 - medulla oblongata

Snipers take head shots to ensure an instant kill. Snipers are trained to aim for the medulla oblongata to sever the spine from the brain.

Snipers refer to the 'T area' of the face, a hit there seals the deal.

The medulla oblongata houses the brain stem which is responsible for organs functioning automatically, the heart, lungs, and central nervous system.
