7-170. The unit’s tempo, momentum, tactical dispersal, use of cover and concealment, and attention to electromagnetic emission control complicate the enemy’s ability to detect and target the main body until contact is made. Once the force makes contact and concentrates its effects against detected enemy forces, it becomes vulnerable to strikes by enemy conventional weapons and WMD. It must concentrate its combat effects rapidly in a meeting engagement and disperse again as soon as it overcomes resistance to avoid enemy counteractions, if the movement to contact is to continue. However, the results of that meeting engagement will determine the specific course of action selected.
