1. Tracer Fire - Leaders in the assault force fire all tracers; their men fire where the leader's tracers impact. The support force positions an automatic weapon on a tripod on the flank nearest the assault element. This weapon fires a burst of tracers every 15 seconds to indicate the near limit of the supporting fires. All other weapons in the support force keep their fires on the side of this tracer away from the assault force. The assault force signals to shift fires to the next position or to a set distance. If required, these rounds can be adjusted well over the head of the assault force to preclude casualties.
2. Luminous Tape or Chemical Lights - Mark assault personnel to prevent fratricide. Do this in a way that avoids enemy detection. You could put luminous tape on the back of the helmet or use small infrared chemical lights (if the enemy has no NVDs). The support force should know where the lead assault force is. If individual Soldier markings do not suffice, use large chemical lights (infrared or visible). Place these on the ground or throw them in front of the assault force. When clearing a trench line, put the lights on a stick and move them with the lead element.
3. Weapons Control Restrictions - Assign weapons control restrictions to reduce the risk to the assault force.
• The element on the right in the assault might be given weapons free to the right flank, because there are no friendly forces there, but weapons tight or hold on the left because another friendly unit is located there.
• The assault force might be restricted to using only shotguns and pistols.
• The assault force might be restricted to no automatic weapons fire on the objective. This ensures that all automatic weapons in use are enemy.
4. Other Techniques - Use the following techniques to increase control during the assault.
• Not allowing flares, grenades, or smoke on the objective.
• Allowing only certain personnel with NVDs to engage targets on the objective.
• Using a magnetic azimuth for maintaining direction.
• Using mortar or artillery rounds to orient attacking units.
• Using guides.
• Reducing intervals between Soldiers and units.
