I rewatched the episode "To The Death". Good episode. One thought I had when the DS9 crew and the Jem'hadar attack the rebellious Jem'hadar, is that it was impossible to tell them apart. How would the starfleet crew know in the hand to hand combat which jem'hadar were on their side? It seems to me that the Jem'Hadar working with starfleet should have painted a color on their uniform or something to ID themselves as "friend", in order to avoid a friendly fire incident.
