Simply stated, the role of fire superiority is to return fire, take cover, and gain fire superiority. Taking these actions is a priority and will help in containing the immediate threat; obtaining fire superiority from point of cover minimizes the risk of new casualties and additional injuries to existing casualties while completing the mission.
Personnel may need to assist in returning fire instead of stopping to care for casualties, and wounded Service members who are exposed to enemy fire should be directed to continue to return fire.
Entering a kill zone to treat or evacuate a casualty is rarely the best action and may lead to additional casualties; establishing fire superiority supersedes those actions.
The best medicine on the battlefield is fire superiority!
