Re: Best tactician? Kirk,Picard, Sisko or Janeway?
It was part of the theme of the film: he was a guy who'd been out of the game for a long time at that point who, having successfully flown by the seat of his pants and gutted out the perils of overconfidence as a younger man, had to come face to face with the reality as a middle-aged man that you can't get away with that forever.
Kirk's leadership by arrogance approach is shown throughout the films. He finally stops in TUC because the stakes are extremely high (and his arrest prevents him from commanding the Enterprise
until Spock is able to piece together the facts surrounding Gorkon's death).
