Well if the Turks aren't Arabs but Western, how about the Arabs kicking the Turks out of Arabia area in WWI?
You might better phrase the question Moslem Army against Christian Army.
As noted the Arabs basically are a Semitic Tribe/"Nation", mostly from the oh say the middle of Lebanon east through Syria and Iraq and winding south to include the "Marsh Arabs" in the Basra to the Gulf Area. West of there you get Egyptians, north Lebanese, Armenians, Turks, Kurds, Assyrians, "Chaldeans??)and east Persians/Aryans. Notice that these quasi racial delineations do not fall easily into the current political delineations nor are all Arabs Shiites. In Iraq, Most Shiites are Arabs and most other "nationalities" are Sunni or Christians. Again the political boundaries do not coincide with religious boundaries.
Get your souvenir program, can't tell the players without a program.
I was in a Armenian Restaurant one time and two different groups of people coming in got in a discussion over a table reserved for a group that hadn't arrived, and somebody called somebody else a Persian and I thought we were going to be in an all out every man for himself movie brawl.
