Special Ops: Snipers [PDF ebook] 

Snipers: skilled, cautious, and keen-eyed shooters who hide and wait for their assigned targets to appear. For a sniper, staying out of view-whether within some bushes or peeking over a rooftop-is job one. But snipers don’t stay hidden for readers of this engrossing book, which pulls back the cover and the camouflage, providing a detailed and inside look at the training, the tools, and the history of how a select few get to be top guns in the U.S. military.
