               e.  Terrain: AO WHITE is composed of rolling ridges and foothills in the eastern and north eastern portion which gradually raises up to form into the mountain chain east of the BA LONG valley. The rolling ridges and foothills area allows limited movement by tracked vehicles and unimpeded movement by foot. The mountainous portion consists of single to triple canopy and offers good security through concealment. This area also has dense undergrowth forest and inclines which average 25 to 35 degree slope. Three roads were constructed through the AO making it feasable to employ track vehicles to certain portions of the AO.
