My only choice is "infantry"...
The game Manual say: Pg 83
" For each rule you define the case were SFTypeGroup X (PreventHitOn) is attacked by enemy
SFTypeGroup Y (PreventFrom) "
But i cant change SfType group
I can only use prevent on SFType Infantry or SFTypeGroup 0
So i cannot create new SFType with prevent on other SFTypegroup
It's normal ?
