Throughout history Jews have always fought for their countries. I heard from a history teacher of mine that during the Byzantine/Persian wars (in the days of the amoraim) they did not do battle on Saturday or Sunday; on Sunday because of the Christian soldiers and on Saturday because of the Jewish ones, who were on both sides. Also, I believe there are quite a few responsa about the very complex problem of what to do as a soldier on the battlefield being perfectly aware that your enemy might be a fellow Jew. It was not uncommon.
