Scourge of War Boards

Most of the headers in the gamedb csv file dumped out at the end of a game are self explanatory, but anyone happen to know what R1,R2,R3,R4,R5,R6 represent?

Also, is there a known list of the possible Status values?

Thanks.

Those are the side, army, corps, div, bde, reg of the enemy unit that was engaged.
