A sand table is just that, a table with high sides and an open top filled with sand. It is used for
landscape simulation to provide a visual reference for planning and coordination. The most common use for a sand table is to devise military
tactics to address a situation and briefing unit members about said plan. In that application little
plastic people and
vehicles are also used, creating a scene little different than that of kids playing in sand with trucks and toys.
The importance of having a visual three-dimensional landscape reference is critical in combat planning, as lines of sight (and fire), available cover, and maneuver goals can be easily determined and explained to others.
