Staff Sergeant R.B. Vickers was a United States Marine who served in China.
Vickers served during the war with China, deployed in Nanjing for four months (June to August), before being transferred to Shanghai for eight months (September to April). The year is not disclosed, although it can be assumed that he rotated back in 2077.
- It is unknown whether Vickers himself wrote the words "Forgive me mama" on the front of his helmet suggesting that he felt remorse as a result of his actions, possibly enlisting and failing to see his mother one last time before she was killed in nuclear fire, or if Randall Clark wrote that after he obtained the armor, and just felt sickened by the war.
- Vickers was not a Desert Ranger.
