AA\A Firing Range
 

In old IL2 you could set the max range of AA and AAA. I assumed the box marked RHide (m) was that box, however after a bit of testing (8 AAA set to 2000) I found whilst they didnt start firing at me until after I had gone within 2000m's they didnt stop after when I'd climbed upto 2500m's...

Is this the right box? There doesnt seem to be any more that fit the bill...
