Ok, on a computer again and got a edited screen shot of the area in discussion. About just under 200 acres total.
Blue Line = Zone boarders, should not enter area from these sides but as you see with the picture the field in the center makes it not entirely necessary.
Red Dots = Stand sites
Specific site I am talking about is the red dot in the top left.
The field is an LZ, all week you will have CH-53's landing and taking off or battalions setting up tents, HMMV, and other stuff for most of the week. Recon battalion is also not even a mile down the road and uses this area for training quite a bit.
Also added a topo if it would help.
