Control Under Fire [PDF ebook] 

Technology and air superiority equals success in modern warfare. But even during the War in Afghanistan, satellite recon and smart bombs cannot replace soldiers on the ground. When a SEAL team Sea Hawk helicopter goes down in the icy mountains of Kandahar, Lieutenant Lester Donovan must make a difficult decision: follow orders or go "off mission" and save his fellow soldiers. With Taliban terrorists at every turn, neither decision will be easy. He’ll need his instincts and some high-tech weaponry to get off of the hillside and back to base alive!
