PART G - DEVELOPING THE COMBINED OBSTACLES OVERLAY
For this step in the IPB process, a map is no longer needed. Terrain factors have
been lifted off a map and developed further. A map substitute has been created.
The remaining uncolored areas represent where a force can move, shoot, and
communicate.
The combined obstacles overlay combines all weather and terrain induced obstacles
to permit more detailed analysis.
Figure 2-15.
Combined Obstacles Overlay.
The overlay integrates all obstacles into one display. This simplifies analysis of
avenues of approach and MCs. All obstacles are cross-hatched and the blank areas
are where forces can move.
The effect of weather on mobility cannot be ignored.
The combined obstacles
overlay reflects average weather/terrain conditions.
Obstacles canalize cross-
country movement.
Excessive precipitation will affect soil density, river stages, and visibility.
Normal SLO-GO conditions might be connected to NO-GO conditions which would affect
force movement.
