2-260. Under normal circumstances, the leader resources dedicated security forces during an attack only if the attack uncovers one or more flanks, or the rear of the attacking force as it advances. In this case, the leader designates a flank or rear security force and assigns it a guard or screen mission, depending on METT-TC. Normally an attacking unit does not need extensive forward security forces as most attacks are launched from positions in contact with the enemy, which reduces the usefulness of a separate forward security force. The exception occurs when the attacking unit is transitioning from defense to attack and had previously established a security area as part of the defense.
