3-109: Flank Positions

Previous: 3-108: Depth and Dispersion

3-109. Flank positions enable a defending force to fire on an attacking force moving parallel to the defender’s forces. A flank position provides the defender with a larger and more vulnerable target while leaving the attacker unsure of the defense location. Major considerations for employment of a flank position are the defender’s ability to secure the flank and his ability to achieve surprise by remaining undetected. Fire control and fratricide avoidance measures are critical considerations in the employment of flank positions. (See appendix B of this publication for more information.)
