Shortcomings in quantity rather than quality of Marine personnel made expansion a problem on 19 July 1950, when General MacArthur sent his third request to the Pentagon for a Marine division with appropriate air. Again the Joint Chiefs referred the matter to General Cates, who was prepared with two plans worked out in detail by his staff--Plan ABLE, providing third rifle companies and replacements for the Brigade; and Plan BAKER, designed to bring the 1st Marine Division up to full war strength by calling reservists to active duty. These plans were based on the personnel statistics of 30 June 1950. The grand total of 74,279 Marines on active duty at that time (97 per cent of authorized strength) was distributed as follows: _Operating Forces_--engaged directly in carrying out assigned missions and tasks 40,364 _Supporting Establishment_--comprising trained administrative and supply personnel 24,552 _Special Assignment_--including all personnel serving with organizations outside the regular establishment 3,871 _Non-Available_--made up of personnel hospitalized, confined, or en route 5,492 ------- Total 74,279 A breakdown of the Operating Forces reveals that the Fleet Marine Force numbered 27,703 men, the security detachments included 11,087, and 1,574 Marines were afloat. Of the 11,853 in FMFPac, 7,779 were in the 1st Marine Division, and 3,733 in the 1st Marine Aircraft Wing. The 15,803 Marines in FMFLant included 8,973 in the 2d Marine Division and 5,297 in the 2d Marine Aircraft Wing.[37] [37] Giusti, I-2. These figures make it evident that the 1st Marine Division could not be brought up to war strength of about 25,000 troops without drawing upon the 33,527 (77 per cent of authorized strength) in the ground forces of the Organized Reserve, and the 6,341 (94 per cent of authorized strength) in the aviation forces. The ground personnel were distributed among these units: Twenty-one infantry battalions; 16 rifle companies; seven 105mm howitzer battalions; five 155mm howitzer battalions; one 155mm gun battalion; two 40mm gun batteries; two tank battalions; three amphibian tractor battalions; one amphibian truck company; one signal company (supplementary); six signal companies; one engineer battalion; 15 women’s reserve platoons. Aviation units consisted of 30 Marine fighter squadrons (VMF) and 12 Marine ground control intercept squadrons (MGCI).
