The rank system in "The Cage" was actually more simplified for the pilot. I can't find a reference picture, but I believe there was two stripes for captain, one stripe for officers and the rest had no braid.I noticed what appear to be stripes on the sleeves of the Cage uniforms. Seems like a good way to show rank.
Someone feel free to correct me or demonstrate more superior Google-fu. For some reason a reference picture is eluding me.
