Hmm.... I'm kinda surprised, because usually these types of commands are the FIRST things people (including me) learn how to do--way before they use addaction or onMapSingleClick.
Anyway, check the online com ref to see how to use all these:
move -> makes group move somewhere
setcombatmode -> sets the group to open fire, hold fire, etc
setbehaviour -> sets the group to 'combat', 'safe', etc
setunitpos -> sets the unit to standing or prone
That is about it. Like I said, check the comm ref to see how to use all these.
