CONDITIONS: Given a casualty on a standard Army litter and a trench obstacle.  Figure 3-44a is a suggested layout for the trench obstacle.

STANDARDS: Evacuate the casualty through the obstacle without causing further injury.

1. Upon reaching the trench, bearer number 1 instructs another bearer to clear any debris or obstacles immediately before the trench, at the trench, and beyond the trench, and to check for booby traps.

2. From the 4-person carry position, bearer number 1 gives the command "Overhead Carry, MOVE."

3. The bearers turn and face the litter (Figure 3-44b).

4. Together, the squad lifts the litter above the top of the trench, keeping it level.

5. The taller bearer at each end of the litter moves between the handles, facing in the direction of travel.

NOTE: If unable to determine which bearer is taller, bearer number 1 will designate a bearer at each end as the tallest.

6. The taller bearer at each end grasps the handles as close to the canvas as possible.

7. The shorter bearer at each end moves under the litter, facing in the direction of travel.

8. The shorter bearer at each end grasps the stirrups, which compensates for the difference in height. If the bearers are of equal height, the bearers under the litter grasp the litter poles to the side of the stirrups nearer the ends (Figure 3-44c).

9. The four bearers proceed through the obstacle completely in the overhead carry position.

10. After passing through the obstacle, the litter squad resumes the 4-person carry position.

11. Did not cause further injury to the casualty.
