Combined Arms Gap-Crossing Operations
� Engineer equipment park (EEP). An EEP is an area near (at least 1 kilometer away) the
crossing site that is used to assemble, prepare, and store bridging or crossing equipment and
material. EEPs are positioned where they do not interfere with traffic to the crossing sites and
where equipment can be dispersed and concealed.
� ERP. The ERP is a checkpoint, manned by engineers, that ensures vehicles do not exceed the
capacity of the crossing means and provides drivers with final instructions before crossing.
ERPs report to the CSC. TCPs are collocated with the ERP to ensure that vehicles clear callforward
areas. As a minimum, each crossing site requires an ERP at its own call-forward area.
� TCP. A TCP is a manned post on both sides of the gap that is used to preclude the interruption
of traffic flow or movement along designated routes. TCP personnel assist crossing-area
headquarters by reporting and regulating the movement of units. TCPs are normally positioned
at critical crossroads, road junctions, staging areas, holding areas, and ERPs.
� Waiting areas. Waiting areas are located adjacent to routes that are used for concealing
vehicles, troops, and equipment while an element is waiting to resume movement. They are
located on both sides of the gap, close to crossing areas. Commanders use the following waiting
areas:
� Staging area. A staging area is a battalion-size area where forces wait to enter the crossing
area.
� Call-forward area. A call-forward area is a company-size waiting area within the crossing
area where engineers make final preparations.
� Holding area. A holding area is a battalion-size area outside the crossing area or a
company size area within it that is used to disperse units during traffic interruptions.
� Attack position. An attack position is the last position within the bridgehead before leaving
the crossing area.
� Assault position. An assault position is the last covered and concealed position where final
preparations are made before assaulting the objective.
� Assembly area. An assembly area is an area that a unit occupies to prepare for an operation
that offers good road access, cover, and concealment.
