How to get every player that not in target player's team?

[Tory Xiao 5]

forEach (playableUnits - [player]);

I use this to get the array containing all players other than the target player

side group _hacked isEqualTo playerSide

and use this to tell if a player is in the target player's group

But how do I get the array that contains every player that is not in the target player's group?

Just off the dome here, but maybe something like:

_grpPlayers = units group player arrayIntersect playableUnits;
_notInPlayerGrp = playableUnits - _grpPlayers;

If by team you mean group you could do:

private _notOnMyGroup = [];
_notOnMyGroup = allPlayers select { group _x isNotEqualTo group player };
_notOnMyGroup //every player not in player's group
