“ A poorly disciplined unit will pass through an area leaving a path of litter. A tracker can use the last rain or strong wind as a measure to show the amount of time it has been there. (5) Camouflaging techniques. Camouflage applies to tracking when the followed party tries to slowdown the tracker; for example, leaving footprints walking backward, brushing out trails, and walking over rocky ground or through streams are ways of camouflaging the trail. (6) Interpreting combat information. The tracker makes a mental image of who he is tracking by using his learned concepts. ”
