APPLICATIONS OF ENGINEER INTELLIGENCE
a. RIVER CROSSING.
For a deliberate river crossing, the engineers would furnish data on the
following:
(1) Weather to be
expected during the operation, with special reference to
possible flooding or
the
movement of ice or debris that could jeopardize the crossing.
(2) Topography and landforms on both sides of the river, including any natural barriers or
obstructions to the advance of our troops other than the river itself.
(3) Location and trafficability of roads on both sides of the river; including bridges or large culverts
that might be destroyed by the enemy.
(4) Trafficability of the soil under weather conditions that may be expected during the operation, with
special attention to areas adjacent to the proposed crossing sites and along the approach routes
(5) Concealment and cover, especially on the friendly side of the river.
(6) Data on enemy defenses on both sides or in the river, including minefields and roadblocks.
Whether or not the enemy can produce artificial flooding of the river.
(7) Possible sites for storm boat or assault boat crossing, footbridges, ferries, vehicular bridges
(floating and/or fixed), and dummy bridges if contemplated. (It is often desirable to have alternate sites for each
installation, with the advantages and disadvantages of each, and a recommendation as to which should be selected.)
(8) Avenues of approach to the assembly and parking areas, the crossing sites, and the successive
objectives of the attacking force.
(9) Sites for engineer dumps, parks, and regulating points.
(10) Location, nature, and amounts of engineer construction and other materials located within the area
of the operation.
(11) Water points for use during the operation.
(12) Data on enemy engineer troops within the area and their capabilities.
(13) Any special data needed in connection with the possible employment of nuclear weapons.
b. AIRHEAD. In connection with the seizure of an airhead, the engineers would furnish data on the
following:
(1) Weather to be expected during the operation, with special reference to high winds, heavy rain or
fog, or other conditions that might affect airlandings and airdrops. (Weather information supplied by engineer
engineer responsibility.)
(2) Topography and landforms within the proposed airhead and along its perimeter, including also any
prominent landmarks, visible from the air, that might guide the attacking force. If time permits, a terrain model of
the airhead may be called for.
(3) Natural barriers and obstructions, especially any located along the perimeter of the airhead that
may be adapted to defensive purposes.
(4) Location and trafficability of roads within the airhead and in the surrounding area; location of
defiles and bridges or large culverts that might be destroyed by the enemy.
