We have always played RED vs. Blue since Halo Combat Evolved. Blue and Red has always had their own team.
In some of the STOCK maps IE: Breaker the Red Team is in a BLUE BASE and The Blue Team is in the Red Base. Are you kidding me??? WTH IS THE REASONING OF THAT!!! SO now I gotta fix it! What a pain in the hiney!!! 
If I cant fixed like it supposed to be then I don’t need to run this map on my server!
Nobody cares and there are no blue/red teams in infinite, the team will be whatever you set your player outline to.
WANNA BET!! Then why do they have a Red Team Called Cobra and a Blue Team Called Eagle! and In Forge you must have min of 2 teams. Guess you never heard of TEAM SLAYER!! and others game like that!! I love it when people talk crap. It just show people how ignorant some people talk crap in forums these days. PERIOD!!! 
If you change your outlines to purple/green then you’ll get team cobra purple and eagle green.
All I see from you is constant complaining but still not a single good map coming from you. Maybe if you actually did something instead of crying you’d be getting somewhere.
