I want to see execution style killings, mass graves, POW's who you can torture and jail. Unarmed civilians that you can mow down for practice.
Seriously though I just got this game off steam. I've seen some youtube vids and ARMA 3 looks awesome. The game just has soo many possiblities it must be overwhelming for bohemia!
Personally though this game looks like you have more fun in multiplayer - nothing beats playing againts REAL players if I was the boss i would scrap the AI and the single player game, maybe focus on a persistant online virtual global battle.
