I am fairly certain the stats for Best Round (B.R) in the theatre area are reporting the same for USMC and PLA. In other words, the USMC stat is a duplication of the PLA stat. Maybe you all know that already, forgot to search first.
You sure did "forget to search" otherwise you might understand how BR for a theater works. Then you wouldn't have posted this because you wouldn't have been wrong.
Try that searching thing.
