I knew of 4 when I was enlisted. 1 officer, 3 enlisted. The officer was not very jewy for a stein, but not brave at all. 2 of the enlisted were what you would call non religious. The 3rd enlisted one was the typical liberal jew who's opinion was slimy and would never commit to anything. Oh, and then there was that Hasidic one in basic training, yeah, he got kicked out.
