U
S Air Force Security Forces airmen at Kunsan AB, South Korea, recently conducted training exercises to sort out tactics and techniques with South Korean anti-aircraft artillery forces that now form part of Kunsan’s defense plan should hostilities erupt on the peninsula once again, reports SrA. Stephen Collier. In the US military, operating an anti-aircraft battery is an Army mission, but in South Korea, it’s an Air Force action and at Kunsan falls to the 38th Fighter Group. The South Korean airmen employ M-61 20 mm Vulcan cannons, each capable of firing 6,600 rounds per second. (Two readers tell us that the Vulcan fires around 6,000 rounds per minute—that’s a big difference.)
