ield Manual (FM) 3-90-2 contributes to the Army and joint community by providing guidance on the conduct of reconnaissance, security, and other tactical enabling tasks. It provides guidance in the form of combat-tested tactics and procedures for tactical enabling tasks modified to exploit emerging Army and joint offensive and defensive capabilities. FM 3-90-2 expounds on the doctrinal fundamentals established in Army Doctrine Reference Publication (ADRP) 3-90. ADRP 3-90 and FM 3-90-1 must be read before reading FM 3-90-2, since that is where the doctrine and tactics for the conduct of offensive and defensive tasks and the art and science of tactics is found.
