Ah, OK, so you want the script to be executed by those three guys, but not necessarily the whole group? If that is the case then do this:
guys = [guy1, guy2, guy3] ;
{[_x] exec "move2.sqs"} forEach guys
or you can do this:
{[_x] exec "move2.sqs"} forEach [guy1, guy2, guy3]
If you want the guys to be passed to the script together (instead of the script running three times for each guy, the script runs once for all the guys).
[guy1, guy2, guy3] exec "move2.sqs"
Then in the script:
_guy 1 = _this select 0
_guy 2 = _this select 1
_guy 3 = _this select 2
or if you want to keep them as an array of units the script would start like this:
_arrayOfguys = _this
