1600 marines could hold territory against a bunch of ill-equipped and unorganized terrorists or insurgents. But 1600 marines ain't holding territory against any major state military.

This is exactly what happened with war in Iraq. The enemy was completely unable to mobilize.
Naturally, if the enemy is already in a war-time posture and already mobilized, you can't employ this tactic for any city, but it might be enough to seize a port or other piece of strategic infrastructure (such as an air field).
Of course this is different when conducting maneuver warfare such as the initial invasion of Iraq in 03, still took 250,000 troops 3 weeks to claim 'victory'.
Here's a great site that has some leaflets from the Iraq war: [2]
