Arma3 simple singleplayer generic mission was just released.
As Proof of Concept (PoC) the main goal was to create a kind of mission, which can looks a bit dynamically using some A3 scripting commands like a createGroup[side, true], BIS_fnc_taskPatrol, BIS_fnc_taskDefend
Sometimes it can be replayed though. Feel free to leave feedback, comment, or ask something about it.
