For purposes of this discussion, 'movement' refers to moving toward or while not in contact with the enemy, and 'maneuver' refers to moving while in contact with the enemy. The techniques are compromises between speed and security. The more secure techniques are slower. The goal of these techniques is to provide the ability to bring suppressive fires quickly in case contact is made and thereby maintain flexibility of maneuver. A common-sense way of thinking about these techniques is that it is foolish to go blindly rushing into a place where the bad-guys might be waiting for you, and that it is always a good idea to have someone backing you up.
Travelling --- This technique is the fastest and least secure of these movement techniques. The vehicles move together as one unit. This technique is used when enemy contact is not expected and when speed is required.
Travelling Overwatch --- The travelling overwatch technique is a bit more secure than the travelling technique. It is used when enemy contact is possible, but speed is required. When moving in travelling overwatch, the unit is divided into two elements. One element moves at a constant speed, while the other element trails and provides overwatch from brief halt positions. The trailing element scans for visual contact while at the halt, clearing any terrain from which the lead element may be engaged. The trailing element must maintain a position such that it may provide suppressive fire and maneuver if the lead element is engaged.
Bounding Overwatch, Alternating Bounds --- Bounding overwatch is slower and more secure than travelling overwatch. It is used when enemy contact is expected or whenever speed is not critical. In bounding overwatch the unit is divided into two elements that take turns overwatching each other from halted positions. While one element is moving the other element is halted and scanning the terrain from which the moving element may be engaged. If the moving element is engaged, the halted element should be able to provide immediate suppressive fire. Both elements should exercise care so that the moving element does not travel into terrain that can be engaged from areas to which the halted element does not have line of sight. When moving by alternating bounds, the elements leap-frog past each other as they bound from one position to the next.
Bounding Overwatch, Successive Bounds --- This is the slowest and the most secure of these movement techniques. This technique is the same as overwatching with alternate bounds. The difference is that rather than leap-frogging past each other, the elements take shorter bounds with the trailing element moving to set positions abreast of the lead element before the lead element moves.
