That would make sense, 33 M-113's, 25 BMP-2's, at least in that area, there's a couple more up north.
How does that work out per battalion, i've got no experience in that issue.
If you don't mind asking, when you were in the military, what type of unit were you in?
Other units i've been looking for is the 16th ID near Gorgan, as well as the few divisions located on the border with Iraq near Kurdistan.
