Other mistake: During the battle near the end of the episode, Sisko is heard saying, "Locking onto the lead ship" but he gives the firing order to Bashir, who is seated at the helm. This implies that the targeting controls and firing controls are at separate stations, which makes no sense.
Other mistake: When the Klingon, Kozak, falls on his knife during his fight with Quark his blood is a deep red. It should be pink like any other Klingon. (00:02:20)
Suggested correction: Klingon blood is only shown as pink in the film Star Trek VI: The Undiscovered Country and in the series Star Trek: Discovery. In the case of the former, the blood was shown as pink/lavender to have it appear alien and also to avoid rating issues (that much blood would have given the film an R rating). This is an inconsistency in the entire Star Trek universe at large, or perhaps only in those two stated instances, and not a mistake in this particular episode as the number of times Klingon blood has been red greatly outweighs the few times it has been shown as pink.
