MACV was reorganized on 15 May 1964, and absorbed MAAG Vietnam within it, when combat unit deployment became too large for advisory group control. A Naval Advisory Group was established, and the Commanding General, 2nd Air Division, became MACV's Air Force component commander. That year the U.S. strength in Vietnam grew from about 16,000 men (10,716 Army) to about 23,300 (16,000 Army) in 1964 (Eckhardt p.43) though logistic support operations were highly fragmented. As a result, the 1st Logistics Command was established.
