May be hard to find good vantage points depending on unit, ONx identify solid looking areas, water...etc . Put on miles until sign starts picking up then slow down.
bomb proof tent - great truck tent, I keep one as a backup in the truck if need to stay a night or get out of weather, dont work well with cot if get 4 man or smaller
For those of you shooting prone off backpack are you taking anything extra in your pack other than typical layers to provide ability to get your gun and elbow stable?
