Try not to be so dismissive of SIX. We know it's the lazy way and bit of a clunky program but it admittedly makes things more convenient for quite many, As an added bonus when you couldn't get your muggle friends to use even simple mods before it's existence you now have something that they are willing to try.
Also the screaming for bcombat.sqf should be considered a BUG, not a feature. The previous versions 0.15? or before worked fine before from the library/files/Arma3 folder where SIX puts every mod (I assume it's called library/files on english systems, it's where most games put save files and other such things). Something has either changed in the mod or bohemia patches so it does not understand using that folder anymore at all. Thus if you wish to play with it on SIX you must make a copy of the bcombat folder and paste it in the steam arma installation folder so it stops asking for bcombat.sqf. Should be considered a bug.
Also out of all the AI mods I really like this one and consider it the best. They're not uber soldaten who spot you and one shot you on sight but when engagement starts you have to take cover. Really digging the balance and the movement on 0.18.1. Also the only AI mod with really active developement still I think. Haven't tried it multiplayer yet but what features don't work in it? Doing a headless client for the AI seems an option if it's resource intensive. Just wondering why the advertisement as only SP mod?
