Marine Helicopters Take the Lead
The truce talks continued to be front-page news in August. Some of the more impulsive newspaper and radio commentators hinted at the possibility of a cease fire before the end of summer. As for the Marine command and staff, they were not so optimistic, judging from this sentence in a report:
“All Division units were notified on 14 August that requisitions had been sent to EUSAK for cold weather clothing and equipment.”
The training period afforded an opportunity to glance back over the first year of fighting in Korea and evaluate the results. There could be no doubt that the war’s foremost tactical innovation so far was the combat helicopter. The Marine Corps had taken the lead in its development when VMO-6, made up of OYs and Sikorsky HO3S-1 helicopters in roughly equal numbers, got into action with the 1st Provisional Marine Brigade in the Pusan Perimeter. Brigadier General Edward A. Craig had the historical distinction, insofar as is known, of being the first commanding general to see the advantages of a “chopper” as a command vehicle.
Evacuation of casualties was the principal job of the rotary-wing aircraft, and 1,926 wounded Marines were flown out during the first year. No less than 701 of these mercy flights took place during the three months from 1 April to 30 June 1951, covering the period of the two CCF 5th Phase offensives and the UN counterstroke. By that time the Bell HTL-4, with its built-in litters on both sides sheltered by plexiglas hoods, had taken over most of the evacuation missions from the HO3S-1.
The zeal of the pilots contributed substantially to the successful results. Captain Dwain L. Redalen gave a demonstration of the VMO-6 spirit at the height of the first CCF offensive in the spring of 1951. During the 13½ hours from 0600 to 1930 on 23 April, he was in the air constantly except for intervals of loading or unloading casualties. Logging a total of 9.6 flight hours, he evacuated 18 wounded men under enemy fire that left bullet holes in the plexiglas of his HTL-4.[260]

Practically all the helicopter techniques put into effect by VMO-6 had originally been developed by the Marine experimental squadron, HMX-1, organized late in 1947 at Quantico. Despite the enthusiasm for rotary-wing aircraft then prevailing, HMX-1 decided that an observation squadron should combine OYs with helicopters. The wisdom of this conclusion was proved in Korea, where the test of combat showed that both types were needed. The OYs were the superiors at reconnaissance and artillery spot missions, while the helicopters excelled at transportation and liaison and evacuation flights.
VMO-6 as a whole was the only Marine organization linking the ground and air commands. An administrative unit of the 1st MAW, the squadron was under the operational control of the 1st Marine Division.[261]
