2-17: Infiltration

Previous: 2-16: Penetration

2-17. An infiltration is a form of maneuver where an attacking force conducts undetected movement through or into an area controlled by enemy forces. The goal is to occupy a position of advantage behind enemy positions while exposing only small friendly elements to their defensive fires. Infiltration occurs by land, water, air, or a combination of means. Moving and assembling forces covertly through enemy positions takes a considerable amount of time. To infiltrate, the force avoids detection and engagement. Since this requirement limits the size and strength of the infiltrating force, and infiltrated forces alone rarely can defeat an enemy, infiltration normally is used in conjunction with and in support for other forms of maneuver. (See figure 2-5.)
