Red vs Blue is not Halo and Halo is not Red vs bLue. They have stated, many years ago that the mention of Master Chief is not meant to be taken seriously as they were just starting the series and had no idea where it would go. The mention of Chief is non-canon.

There are so many things in Red vs BLue that contradict Halo making it impossible for it to take place within Halo.
