Don't play much squads but I've played a few times.. I don't think there is one since it is part of matchmaking. You can try squads vs squads but you can't really invite a friend to a match. You can try local play, though.
Is it possible to play agains a friend and there squad i have tried every way i can think of, or is it just random choice regardss johndamod
There is actually no way on playing with your friend on Squad vs Squad, if you're referring to that game mode, since the player that you will be up against is being picked up randomly. Well, as for Local Play, there is no way as well on playing with your friend's squads since you can only play one on one or the two of your vs bots.
