From my extremely limited knowledge of the field derived from Shooter by Gunnery Sgt. Coughlin USMC that report is difficult to believe. Coughlin, who is the Marine Corps's top ranked sniper generally worked with a small "support" team but was really the only sniper. His commanding officer generally served as his spotter and a few other guys kept the building they were working from secure. The book emphasizes the traditional importance of cover that not only concealed the snipers position but offered protection from enemy fire; after a few shots the sniper would find a new location such that his position was not “made” by the enemy. The main argument of the book was for the development of a mobile sniper strike force that would include a sniper, a spotter, a few “grunts” and a vehicle that would allow for rapid deployment to new positions rather than laying in wait for the enemy for hours of days unsupported.
