Rimas Nelsson (b. ???? - d. ????) was a Sho-sho within the Draconis Combine Mustered Soldiery and in 2583 he succeeded Sho-sho Masao Igushi as commander of the Draconis Combine Auxiliary Corps supporting the Star League task force during Operation UNION HOLD, the Star League invasion of the Outworlds Alliance during the Reunification War. Nelsson was from the Rasalhague Dominion of the Draconis Combine and was considered a rising star in the DCMS; he replaced Igushi after Igushi failed to capture the Alliance worlds of Milligan's World, Prinis Prime and Quantraine, but would be unable to conquer any Alliance worlds himself during the remainder of the war due to a lack of logistical support and supplies.
