In any and all recovery operations, use the following
STEP 1. RECONNOITER AREA
Check the terrain for an
approach to the load,
then determine the
method of rigging and the
availability of natural anchors. As with a tactical mission,
a recovery crew must know the problem before making
Make a complete ground survey of the area, then select
the best route of approach to the disabled vehicle to
prevent possible disablement of the recovery vehicle.
When selecting the evacuation route, ensure the military
route classification number will support the combination
vehicle classification (recovery plus towed vehicle).
Refer to FM 5-36 for further information.
STEP 2. ESTIMATE THE SITUATION
Estimate the resistance created by the load and deter-
mine the capacity of the available effort. For most recov-
ery operations involving winching, the available effort
would be the maximum capacity of the winch.
STEP 3. CALCULATE RATIO
Compute an estimated mechanical advantage for the
rigging by dividing the resistance of the load (STEP 2) by
the available effort (the capacity of the winch).
