1. Combat engineers can undertake force support engineering tasks but with limitations.
2. Combat engineer (sapper) units may construct tactical obstacles, defensive positions, fixed and float bridges; repair CPs, LOCs, tactical routes, culverts, fords, and other selected general (horizontal and vertical construction-related) engineering tasks. Combat engineer units also provide engineer support for gap (to include river) crossing operations, assist in assaulting fortified positions, and conduct breaching operations. Airborne and air assault capable engineer units also have the unique ability to employ air-droppable rapid runway repair kits in support of forcible entry operations. The more specialized combat engineering capabilities of assault bridging, breaching, and route and area clearance are added to the organic engineer capabilities in BCTs (or to deployed core sapper companies) to allow them to accomplish their broader mission requirements.
