SITE REQUIREMENTS AND LAYOUTS
Site selection for boat operations depends on several factors. It is usually a
compromise of tactical and technical requirements. A careful survey of the proposed
boat launching site should be made by reconnaissance, not by the operator/crew. Site
selection is the result of a commander's strategic decision based on tactical
requirements. However, the operator/crew must understand and observe the site
requirements when performing boat operations.
Tactical Requirements -- The ability of the U.S. Army to cross a river, gully, or
ditch quickly and efficiently is critical. A float bridge will be used where conditions
warrant a crossing and no other method of crossing a gap quickly is available to
advance army forces.
Boat site preparation. Where tactically and strategically possible, perform a
preliminary study and site selection checks to determine the proposed launch
site of the boat prior to marking out the site.
proposed boat launch location.
photographs, and personal aerial reconnaissance. If possible, seek the advice of
friendly local civilians.
Site reconnaissance. Reconnaissance is required to:
1. Select a suitable site.
2. Measure the bank heights and slopes.
Hasty reconnaissance. This is carried out when it is not possible to take
measurements with instruments and when access to the far bank is not possible.
Make best estimates of bank heights.
Deliberate reconnaissance. Deliberate reconnaissance should always be
carried out where possible, following standard practice. Determine the relative
bank heights by means of a suitable instrument.
