Errors made by characters (possibly deliberate errors by the filmmakers): During the attack on the USS Saratoga, we see the Borg cube fire a phaser at the ventral (bottom) side of the ship, yet when Sisko asks for a damage report, the Bolian officer says "Damage to Decks 1-4". Decks 1-4 would be on the dorsal (top) side of the ship, which was not where the Borg phaser was shown to strike at.
