CROSSING-SITE COMMANDER
E-25. Each crossing site has an engineer, typically a company commander or a platoon leader, who
handles the crossing of the units sent to the site. Normally, the crossing-site commander (CSC) is the
company commander for the bridge unit operating the site. He commands the engineers operating the
crossing means and the engineer regulating points (ERPs) at the call-forward areas for that site. He
maintains the site and decides on the immediate action needed to remove broken-down or damaged
vehicles that interfere with activities at the site. The CSC is responsible to the CAE and keeps him
informed on the status of the site.
UNIT MOVEMENT CONTROL OFFICER
E-26. Each battalion or separate unit commander designates a movement control officer who coordinates
unit movement according to the movement control plan. He provides staff planners with detailed
information on unit vehicle types and quantities.
CONTROL MECHANISMS
E-27. A major control mechanism category is graphic control measures. The commander uses the
following graphic control measures (see figure E-5) to delineate AORs for subordinates and to ease traffic
control:
� RLs. RLs are used to delineate the crossing area. RLs are located on the farside and the
nearside, within 3 to 4 kilometers of the gap, and indicate a change in the headquarters that is
controlling movements. Typically, they are graphically identified as PLs and located on easily
identifiable terrain when possible.
� Crossing areas. Crossing areas are normally brigade-size, controlled-access areas for
gap-crossing operations that are designed to decrease traffic congestion at the gap. They
normally extend 3 to 4 kilometers on each side of the gap, are METT-TC-dependent, and are
defined by BCT boundaries and RLs.
