FM 90-13 (ARMY FIELD MANUAL), RIVER-CROSSING OPERATIONS (26 JAN 1998) [MCWP 3-17.1]
FM 90-13 (ARMY FIELD MANUAL), RIVER-CROSSING OPERATIONS (26 JAN 1998) [MCWP 3-17.1]., Field Manual (FM) 90-13 describes how divisions and brigades conduct river crossings. It
shows the relationship to corps operations, where appropriate, and includes details for lower
echelons to support the brigades. It provides doctrine, tactics, techniques, and procedures
(TTP) in one reference to accomplish this special operation.
The corps assigns missions and provides the necessary support and equipment. The divi-
sions normally assign bridgehead objectives and control movement across the river. The bri-
gades are the bridgehead forces that execute the crossings, either independently or as
elements of a larger force.
River-crossing skills and knowledge are highly perishable. As with many other tactical oper-
ations, they require constant practice in planning and execution. There are relatively few
opportunities to train with the frequency needed to keep a high degree of proficiency in this
tough operation. For that reason, this manual includes considerable detail on techniques
and procedures.
A river crossing is a special operation in that it requires specific procedures for success
because the water obstacle prevents normal ground maneuver. It demands more detailed
planning and technical support than normal tactical operations. It also features specific con-
trol measures to move the force across a water obstacle. This obstacle may be a river, a lake,
or a canal. Unlike other obstacle types, the water obstacle remains effective during and after
the crossing operation. See FM 90-13-1 for other counterobstacle operations.
As in the past, the United States (US) Army conducts river crossings within the context of
its basic doctrine. This manual applies the current Army-operations doctrine described in
FM 100-5 to river crossings. It incorporates recent developments in command and control
(C2) for command-post (CP) facilities and the military decision-making process. It also aligns
US doctrine more closely with ongoing standardization efforts in the North Atlantic Treaty
Organization (NATO).
