His full name is Tarmicle Roving III. Born the son of a distinguished soldier in Hokkaidō, Japan, Tarma joined the army's training college for special tactics and combat straight out of Junior High. When he was 20 he rescued the president and used this to get himself transferred to the Peregrine Falcon Squad (PF Squad) where he became best friends with Marco Rossi and upon learning Marco was to go and fight in the Great War (a fictional battle in the future) he volunteered and fought and survived the war alongside his friend leading to his promotion to Captain, the rank he still holds as of Metal Slug 6.
Tarma is an expert motorcycle engineer and builds custom bikes for fun in his spare time. He had intended to retire and set up a shop, but his requests for a discharge from the military have always been denied.
