Intelligence (Marine Corps Doctrinal Publication McDp 2)

"Marine Corps Doctrinal Publication (MCDP) 2, ""Intelligence,"" describes the theory and philosophy of intelligence as practiced by the United States Marine Corps. It provides Marines a conceptual framework for understanding and conducting effective intelligence activities. The Marine Corps' view of intelligence is based on our common understanding of the nature of war and on our warfighting philosophy as described in MCDP 1,Warfighting.
""Intelligence"" discusses the effective use of knowledge about the enemy and the environment in support of military decision-making. Intelligence acknowledges that uncertainty pervades the battlefield and that our best intelligence efforts can only reduce, not eliminate, uncertainty."
