Private Shinji Kuronaga is a Tanker with the nickname "Carnage".
Kuronaga is attached to Downfall Company, coming under Frane Harth's One-Four Bravo fireteam. This puts him in the meat-headed daily company of:
Given that Downfall was deployed to the surface during the Second Liberation of Mibes, it is reasonable to assume that Kuronaga was one of the Tankers encountered there by Elm Caden and his team. The same can be said of Operation Keystone, which visited the surface of Guathelia, and the mission to the Viskr homeworld (→LOTD, TRD).
Kuronaga was present during the investigation at Forge Ruinous, when MAGA and Tanker assets were deployed to the surface of Lopama in order to discover the whereabouts of a missing Tanker platoon. It is likely that the was the first person to have contact with the Rasas who were present in the facility (→FSS).
Carnage was one of those fortunate enough to survive Operation Sabre on the surface of Palanda Ire. He was also a member of a ground-based strike team during the Siege of Damastion (→FSS).
