^^^ Sch$effer, I feel so stupid now... lol... I knew that. But haven't played the game in a while so I forgot (get off my case). So yes you can. lol... Invite your friend to Squad vs. Squad, and select play game, and boom. Playing against a friend in Squads.
And to think I wasn't drunk earlier (only an ounce shy of a fifth, lol). Next time, I will do my research. lol. And not go from memory, as it's s**t anyway. Good luck on the Squads with a friend.
