They are also aware of where the new site is located and when operations begin there. Supported units recognize that support operations are degraded while elements move. To minimize support disruption, however, support battalion elements move in echelons. Operations at the new site begin before the old site is completely closed out. However, downloaded supplies at supply points and disabled equipment at maintenance sites may cause mobility problems.
Personnel evacuate disabled equipment or repair it before the move.
The support battalion elements keep supplies uploaded as much as possible. A close column is one in which elements are formed as compactly as possible. Usually, there are 67 vehicles per kilometer. This reduces time and allows better control with fewer guides, escorts, and markers. However, a close column is easier to detect, causes traffic congestion, and makes quick dispersion difficult.
