Red worked for Red mann and Blue worked for Blu mann.
They disbanded once Red and Blu mann were killed by their little brother Gray mann after Gray tried to get them to stop fighting over useless Gravel
Some of Red team and Blue team are dead, at least the ones that didn't get their Meet the Class episodes that tied them to other characters like Meet the Spy, which had Red Spy fucking Blu scouts mom or more episodes that made their version more known like Red Pyro or had separate classes interact with the opposite team like what

According to the guys working on the comic there's only ever been RED team which is why there isn't any BLU seen ever. There was a gamemode where the losers were trapped in hell so just assume BLU is in hell.
Also in the MvM gamemode, Valve couldn't assed to code the sentries in such a way that they wouldn't immediately shoot at BLU players, so in-canon they had BLU team switch to RED to avoid this problem, also in MvM, the mercs were rehired by Saxton to protect
Mann.Cobasically nothing makes sense because it's several people doing their own thing and only treating certain things as canon
