Key point: North Korea has worked hard to attain long-range military capabilities and a survivable nuclear deterrent.
The United States has substantial air, land, and sea forces stationed in South Korea, as well as several units based in Japan and the western Pacific earmarked for a Korean contingency. Together, these forces far exceed the firepower of North Korea’s armed forces and represent a powerful deterrent not just against Pyongyang but any potential adversary in the region.
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.
