WESLEY: You've had a singular honour conferred on you, Jim. You're going to be the fox in the hunt.
KIRK: What's that?
WESLEY: War games. I'll be commanding the attack force against you.
KIRK: An entire attack force against my ship?
WESLEY: Have you heard of the M-5 multitronic unit?
KIRK: That's Doctor Richard Daystrom's device, isn't it? Tell me about that.
SPOCK: The most ambitious computer complex ever created. Its purpose is to correlate all computer activity aboard a starship, to provide the ultimate in vessel operation and control.
WESLEY: How do you know so much about it, Commander?
SPOCK: I hold an A-7 computer expert classification, Commodore. I'm well acquainted with Doctor Daystrom's theories and discoveries. The basic design of all our ship's computers are Doctor Daystrom's.
KIRK; What has all this got to do with the Enterprise?
WESLEY: You've been chosen to test the M-5, Jim. There'll be a series of routine research and contact problems for the M-5 to solve, plus navigational maneuvers and the war games problem. If the M-5 works under actual conditions as well as it has under simulated tests, it will mean a revolution in space technology as great as warp drive. When your crew has been removed, the ship's engineering section will be modified to contain the computer.
KIRK: Why remove my crew?
WESLEY: They're not needed.
KIRK: How much security does this gadget require?
WESLEY: None. Doctor Daystrom will see to the installation himself and he'll supervise the tests. When he's ready, you'll receive your orders and proceed on the mission with a crew of twenty.
KIRK: Twenty? I can't run a starship with twenty crew.
WESLEY: The M-5 can.
KIRK: And what am I supposed to do?
WESLEY: You've got a great job, Jim. All you have to do is sit back and let the machine do the work.
