Light, Simple but Rough!
Improve AI's behaviour, fighting skill and player détection
The Team R3F witch have done the R3F Weapons Pack release here a powerfull Addon.

"Improving AI behaviour on ArmA serie is a never-ending quest. We early noticed a "lack of communication" between ArmA3's AI in combat zone.
To correct this, {R3F} Mapoule release here a script R3F_AiComTarget which has been specialy developed for multiplayer mod.
It has been tested 24/7 on a multiplayer server with Domination on and also on private edited operation, by daytime and night time.
You'll notice an impressive result : Alerted AI will never leave you any rest, and you'll survive only with a clean coop gameplay, with proper weapons, or with good fall-back uses." {R3F} Killjo
