This is an interesting piece most useful to remind me we are still at the DMZ:
The tanks and their crews, from Dragon Company of the 1st Battalion’s 72nd Armor Regiment (1-72 AR), are a small but lethal component of the U.S. Army's 2nd Infantry Division stationed close to the tense border separating North and South Korea.
We only have a brigade of the division in South Korea. And the article implies that only a portion of that brigade is on the DMZ.
I'm not sure when all our troops will finally be off the line, but we aren't there yet.
UPDATE: Ah, I found an old post that said we'd be off the DMZ within 5 years. Since that was a November 2007 post, we're overdue.
