Evacuation Code

Did anybody else notice the evacuation code given by the commanding officer to the communications guy when they're on that rocky hillside?

"Radio stable base, tell em we need evac from that point in 40 minutes...the code is Romeo-2-Delta-2."

As in R2D2.

Gotta love a clever little Star Wars reference. Well, maybe you don't "gotta" love it, but still.
