Sniper: noun
A person who shoots from a hiding place, especially accurately and at long range.
“The terrorist was killed by a Marine sniper’s bullet in Iraq.”

The sniper is one of the most effective and accurate tools on the battlefield.

By using a sniper you don’t accidentally kill civilians which is quite common to the drone warfare of today.

The first time I was exposed to the world of snipers was when reading Carlos Hathcock’s book, Marine Sniper. From that moment, I was hooked but the sniper of Vietnam is very different from that of WWII, Korea, Iraq, and Afghanistan.
