Most brigade operations will commence or terminate in an assembly area. Consequently, the brigade can plan on conducting frequent tactical movement into and out of assembly areas on a routine basis. The tactical road march is a unit move in a combat-ready posture normally conducted in the combat zone. Enemy contact is possible either during the march or soon after arrival at the unit's destin-ation.
Units normally move by tactical road marches to assembly areas to prepare for combat operations.
The S3 is responsible for planning tactical road marches. The following paragraphs are definitions used in movement and tactical road marches. Close Column Vehicles are spaced approximately 25 meters apart. Open Column Vehicles are spaced 50 to 100 meters apart. Normally used during daylight, open column can be used at night with proper night-vision equipment.
