US Army/Marine Counterinsurgency Field Manual

Based largely on strategic methodologies devised by the current over all commander in Iraq, General David Petraeus, this manual is a much needed revision of counterinsurgency (COIN) principles. Its unique premise is that the key to effective counterinsurgency is the protection of civilians. The size of the counterinsurgency force is to be calculated not solely by the number of enemy faced but also by the number of civilians to be defended. The witness to the effectiveness of this strategy devised by General Petraeus is the current success that counterinsurgency forces are currently having throughout Iraq.
