(tunnel reconnaissance) (4-63)
FRAME 4-64. INFORMATION FRAME.
In Lesson 3 we discussed the tunnel symbol used on the route reconnaissance overlay (see Frames 3-92 to 3-
101). This symbol contains the essential tunnel information which must be reported, including the serial number,
location, overhead clearance, width, length, and bypass conditions. When more detailed information is needed, a
deliberate reconnaissance is performed and the information obtained is recorded on the Tunnel Reconnaissance
Report, DA Form 1250.
The site plan gives the alinement of the ford and its approaches with respect to the stream. Any critical terrain

the stream are always indicated.
