The 10th Cavalry Regiment is a unit of the United States Army. Formed as a segregated African-American unit, the 10th Cavalry was one of the original "Buffalo Soldier" regiments in the post-Civil War Regular Army. It served in combat during the Indian Wars in the western United States, the Spanish-American War in Cuba and in the Philippine-American War. The regiment was trained as a combat unit but later relegated to non-combat duty and served in that capacity in World War II until its deactivation in 1944. The 10th Cavalry was reactivated as an integrated combat unit in 1958. Portions of the regiment have served in conflicts ranging from the Vietnam War to Operation Enduring Freedom and Operation Iraqi Freedom. The current structure is by squadron, but with the 1st and 7th Squadrons recently deactivated, the 4th Squadron is the only 10th Cavalry Regiment unit in active service. It is assigned to the 3rd Armored Brigade Combat Team of the U.S. 4th Infantry Division at Ft Carson, Colorado.

Trying to end a three-game skid, the 49ers flew to Qwest Field for an NFC West rematch with the Seattle Seahawks on Thursday night. In the first quarter, the Niners started off bumpy as Seahawks RB Shaun Alexander got a 3-yard TD run for Seattle's early strike and the only score of the period. In the second quarter, San Francisco would get a field goal before halftime as kicker Joe Nedney nailed one from 39 yards out. After a scorless third quarter, the Niners were in full force as QB Alex Smith completed an 8-yard TD pass to rookie TE Vernon Davis. Afterwards, Smith would complete a 20-yard TD pass to RB Frank Gore. Then, the 49ers wrapped the game up with Smith getting a very easy 18-yard QB sneak for a touchdown. Seattle would get one more score as QB Matt Hasselbeck completed a 22-yard TD pass to TE Jerramy Stevens. Fortunately, the Niners would get the win and the season sweep over the Seahawks. With the win, the 49ers improved to 6-8
