According to both Ryan and McNab, the weight of their equipment required the patrol to "shuttle" the equipment to the observation post. Four members would walk approximately 300 m, then drop their bergens and wait. The next four would move up and drop their bergens, then the first four would return for their jerry cans of water and bring them back to the group, followed by the second four doing the same. In this manner, each member of the patrol covered three times the distance from the drop off to the observation post.
