Throughout history, the details of military technology have driven tactics. Often we end up with what might be called a "classic tactic".
I'm thinking of things like: In the age of sailing ships, the classic tactic was "crossing the T": maneuver so that the broad side of your ship is facing the enemy's bow or stern, so that you can fire with a large number of guns while he can only fire with one or two.
With fighter aircraft, the classic tactic is "stay on his tail": position yourself directly behind the enemy, so that your relative velocity is as small as possible and you can easily see him while he has difficulty seeing you, and as most weapons fire forward you can shoot at him but he can't shoot at you.
With muskets, the classic tactic was "the line", or for the British who carried this tactic to its limits, "the thin red line": Form your troops into a long line and fire simultaneous volleys, so that even though your weapons are horribly inaccurate you send a wall of lead at the enemy and have a good chance of hitting SOMETHING.
So we generally suppose that future military spacecraft will use missiles and/or lasers or some other sort of beam weapon. What would be the "classic tactic" of such ships? Anything more interesting than "start shooting once you get in range"?
