What Weapons Would the U.S. Military Use Against North Korea?
The first U.S. forces that would be involved in a North-South Korean conflict are those currently based in South Korea. On the ground, the U.S. Army rotates a new armored brigade into South Korea every nine months—currently the 2nd Brigade Combat Team, 1st Cavalry Division. Each brigade is manned by 3,500 soldiers and consists of three combined arms battalions, one cavalry (reconnaissance) battalion, one artillery battalion, one engineer and one brigade support battalion. Armored brigade combat teams typically consist of approximately 100 M1A2 Abrams tanks, 100 M2A3 Bradley infantry fighting vehicles and eighteen M109-series self-propelled howitzers.
The other major component of America powenr in Korea is U.S. tactical aviation. The U.S. Air Force maintains the 51st Fighter Wing  at Osan Air Base, consisting of the 25th Fighter Squadron at equipped with A-10C Thunderbolt II ground attack jets and the 36th Fighter Squadron with F-16C/D Fighting Falcon fighters (about forty-eight aircraft in all). The 8th (“Wolfpack”) Fighter Wing  at Kunsan Air Base consists of the 35th and 80th Fighter Squadrons, which fly a total of forty-five F-16C/Ds. The A-10Cs have the mission of close air support, while the F-16C/Ds are responsible for air interdiction, close air support and counter-air.
