Cover the front... and the rear!

RIMMER: Uh, Kryten, take point. I've seen those movies. It's always the guy in the lead who buys it first. You take the front. KRYTEN: Well, if it's movies we're talking about, sir, in my experience it's usually the poor fellow who's bringing up the rear that gets picked off first, so the others aren't aware that they're under attack. RIMMER: You're right, you're right. Can you take the front and the back, so I can go in the middle? KRYTEN: I'll do my best, sir.
