From:Sent: Thursday, November 29, 2001 11:17 PM Subject: NewUnit The 618th ACWS was operational in 1950 at Miho Air Base in Japan. I believe that the 5th AF aircraft early warning function in Korea was done by the 502nd Tactical Control Group. I was a member of the 618th ACWS (Radar site) at Miho 1948-50. Went to Korea soon after war began - assigned to Hq Sq 5AF at Taegu and Seoul, MOS 166, Powerman. Would like to hear from anyone who served in these units. Harry Smith, MSgt, USAF(Ret)
