Guys thanks for your replies.
@Komuna
Komuna my friend thanks a lot. Actually now I was working on some AI scripts dealing with reactions of units in battle i.e. when an enemy grenade falls near a unit or when a unit throws a grenade and other units of his squad are about to move towards the place the grenade was thrown etc. I have some good results up to now but I'm still working on it. When I prepare something final you'll be the first to know.
