His name is 'Aram Yossarian' on his dog tags in the movie poster
Yossarian's first name is "Aram" on his dog tags in the movie poster. "My name is Aram" of course, is a famous short story by the Armenian-American author William Saroyan. Yossarian is an Aremenian name (or Armenian-like), though he says he is Assyrian in the book and movie. (Heller once said, I believe, that he didn't really know what an Assyrian was at the time he wrote the book. In the sequel, "Closing Time", Yossarian is an Armenian American who has joked that he was an Assyrian. It's important as Armenians, of course, were the victims of one of the greatest genocide aside from the Holocaust and had their own diaspora, like the Jews.
