React to Contact

When your squad/platoon receives fire from the enemy the following drill should be executed:

Step 1 (Cover) Take up the nearest cover and return fire. Identify the enemy, determine if the squad/platoon can properly engage the enemy, and if the fireteam/squad in contact can suppress the enemy. If not, deploy additional fireteams/squads to gain suppressing fire. If all fireteams/squads are deployed, the squad/platoon commander moves into position to observe and suppress the enemy. No further orders will be made and the squad/platoon will be used as a base of fire for the platoon/company.

Step 2 (Maneuvering) Determine avenues of approach to the enemy and deploy a fireteam/squad into position to seize the enemy position. Make sure the base of fire element keeps the movement covered or obscured from the enemy.

Step 3 (Assault) Report to the platoon/company commander. Take command of the assaulting fireteam/squad and signal the base of fire element to shift fire away from the area about to be attacked. Seize the enemy position.

Step 4 (Reorganize) Redistribute ammunition and supplies. Fill any sensitive vacancies and move the base of fire element into position to cover the most likely avenue of approach.
