From what I can find it was Captain Chuck 'Sly' Magill who was attached to the 58th Fighter Squadron flying F-15's. He shot down a MiG-29 with an AIM-7 on the first day of the war. This book, on my short list to buy, should have a good description of the engagement in it. The last Marine ace was an exchange guy too, Major John Bolt. He shot down 6 MiG-15's flying USAF F-86's in Korea to add to the 6 Zeros he shot down in WWII. John Glenn also shot down 3 MiG's in Korea with the USAF as well.
