Ptolemaic armies vs. Roman Legions (circa 50 b.C.)

[Komanos]

There definitely were. There were large numbers of Jews, Arabs, and Anatolians in the Ptolemaic army. Most of the Jews in the actual army would have been serving in units with men of other ethnicities. In the conscriptions for the Alexandrian War, it wouldn't surprise me at all if units were raised from the quarters and smaller neighborhoods, so Jews probably fought as units together in that particular instance.
