Tactics
FM 3-90 is the Army's tactics manual for offensive, defensive, and enabling operations. It merged the two 2013 volumes of FM 3-90 into one book, so reconnaissance, security, and other enabling tasks now sit with the offense and defense chapters. It is the detail behind ADP 3-90.

Doctrine Primer
ADP 1-01 explains what doctrine is, what it is not, and how the Army organizes it. It walks through the publication hierarchy, how terms and symbols are approved, and how doctrine relates to policy and to tactics, techniques, and procedures. Start here if the ADP, FM, ATP, TC alphabet soup does not yet make sense.

Offense and Defense
ADP 3-90 holds the fundamentals of offensive and defensive operations: the forms of maneuver, the types of attacks, and the forms of the defense. It is the doctrinal parent for FM 3-90, Tactics, which carries the detail. If a board asks about the four types of offensive operations, this is where the answer lives.
