I was afraid it would be something like that, but I was hoping for some 
halfway-decent hard numbers (e.g. from an old army manual or some such).

What prompted my request was my working on rules for hiding, chases, etc. 
plus a look at the D&D 3.5e rules for terrain - in particular the maximum 
distances for "detecting the nearby presence of others" in that system. The current 
edition of D&D give what strike me as very short distances: 2d6x10 *feet* in 
heavy forest to 6d6x40 *feet* on the open plains. (I might buy the heavy forest 
distances, but ~250 meters *maximum* spotting on an average roll on the open 

Anyway, I'd prefer not to crib from other games, whether D&D or Squad Leader, 
but to use "real world" distances (if such exist) and then mangle them for 
playability while knowing just how unrealistic I'm being. I also expected that 
I'd have to make some pretty drastic simplifications, but I figured that if I 
could get the median distances sorta-kinda right, for walking man-sized figures 
who aren't particularly trying to hide, the rest would follow.
