Timelines A, B: 1970
The outbreak of the Vietnam War sees Charles’ school shut down as its students are signed up for military service, driving Xavier to alcoholism and abuse of a drug that lets him walk, in exchange for dampening his mutant powers. (X-Men: Days of Future Past)
Simultaneously, James Howlett and Victor Creed are serving in Vietnam, but are recruited by William Stryker alongside several other mutants to form a black ops squad called Team X. James adopts a new alias, Logan, after his real father, and earns the codename Wolverine in the service of Team X—but quits after several years, disagreeing with Stryker and the Team’s violent ethos. (X-Men Origins: Wolverine)
