During the buddy drag in a maneuver under fire event, which action should Marines perform?

In the buddy drag during a maneuver under fire event, obtaining a grasp on both forearms is the most effective technique. This method allows for better control of the casualty, as grabbing both forearms provides stability while also enabling the rescuer to maintain balance while moving. It is important to use both arms to ensure the casualty can be pulled effectively and reduces the risk of further injury to both the rescuer and the casualty.

The other methods would not provide the same level of control or efficiency. Lifting the casualty by the shoulders might not be feasible in a combat situation where time is of the essence, and it may cause discomfort or further injury to the person being dragged. Using only one arm for dragging could lead to uneven weight distribution and difficulty in maneuvering quickly and effectively. Securing the legs first may lead to a loss of control and increase the risk of dragging the casualty incorrectly or ineffectively.

Overall, grasping both forearms allows for a secure hold and maximizes the ability to maneuver swiftly while keeping the casualty safe during the drag.
