Today, the Pentagon announced the first of the 30,000-35,000 surge troops headed to Afghanistan. Secretary of Defense Robert Gates began working on the orders last week, he told PBS’ Jim Lehrer News Hour, on the flight back from the president’s speech at the United States Military Academy at West Point, N.Y. Dec. 1 where he announced the strategy. In all, the Pentagon announced 16,000 troops.

From the Marines, the three deployment groups:
 
Task Force 1st Battalion, 6th Marines, based out of Camp Lejeune,
N.C., with approximately 1,500 Marines, deploying before the end of December
2009
 
Regimental Combat Team-2, headquartered at Camp Lejeune, N.C.,
with approximately 6,200 Marines, deploying early spring 2010.
 
I Marine Expeditionary Force (Forward) headquarters from Camp
Pendleton, Calif., with approximately 800 Marines, deploying spring 2010.
 
These units will bring the total number of Marines deployed to Afghanistan
to approximately 19,500.

And for the Army:
lst Brigade Combat Team, 10th Mountain Division, Fort Drum, N.Y., with approximately 3,400 soldiers, deploying spring 2010. They are tasked with training Afghan security forces

In addition, another 4,100 combat support troops from several services, including military police will be deploying spring 2010.

UPDATE: Dear readers. A couple of my numbers were off by 200. I have corrected them. My apologies.
