What does the Red Elite mean in Halo 3 campaign?

[Ben]

I thought the red elite in Halo 3 campaign meant you had the worst connection in the party. Am I right?

 

[Jarred]

the red elite is the fourth player so just like the other guy said the fourth elite has different armor though and he doesnt do anyin special

no it just means that you are the 4th player, Master chief is host (not to be confused with party leader) Arbiter is 2nd player, and Blue Elite is third.
