Americans in Foreign Militaries

[The Wizard]

Mickey Marcus, the first man to be appointed to the highest rank of aluf (major general) by the State of Israel. One of the thousands of machal fighting alongside the Yishuv during the Israeli War of Independence. He was killed by a sabra who did not speak English or Yiddish (which were the only languages Marcus spoke) and consequently couldn't demand a password from him at a perimeter.

They made a movie about him in the '60s called Cast a Giant Shadow. For those not entirely happy with Israel in this present day and age, be warned -- it's strong on the Zionist romanticism (at least, I think it is; haven't seen it myself).
