One of the key battlefield tasks is avoiding being surprised by the enemy. The way to do that is to maintain contact with him. If contact is lost, it should be reestablished as soon as practical.
The way to do this is known as Movement to Contact. As the video explains, this is an offensive task. In effect, it’s something like a hasty attack, except you don’t really know where you’ll be conducting the attack.
Mind you, careful analysis of the terrain, and a fair appreciation of the enemy order of battle can often give you a pretty good idea where contact is likely.
A doctrinal here- to fix an enemy is to place sufficient fires upon him as to preclude him from either disengaging, or maneuvering.
While the video is geared toward the Combined Arms Battalion, Movement to Contact is a mission that can be conducted by light forces as well. Indeed, even Attack Aviation does it. The tactics, techniques and procedures (TTP) differ somewhat, but the fundamentals are the same.
