The time interval between a request for Marine air support and the actual delivery varied according to local conditions, but the ground forces seldom had cause for complaint. All-weather Squadron VMF(N)-513, based at Itazuke, Japan, was prevented by reason of faulty communications and liaison from responding to every request for dawn, dusk or night support during early Brigade operations, but such missions were flown effectively in the Naktong Bulge. Meanwhile, the Corsairs of VMF-214 and VMF-323, orbiting on station and always available for short notice employment, gave fresh proof that the Navy-Marine concept of carrier-based tactical aircraft was sound in practice.

Demands on the time of the original 4 helicopters of VMO-6 made it necessary to fly 2 more machines in from Japan. The rotary-wing aircraft had so many “firsts” to their credit in the Pusan Perimeter that a major tactical innovation was obviously in the making. The flights of General Craig, Colonel Snedeker and Lieutenant Colonel Stewart alone were enough to indicate that the helicopter was capable of working a revolution in command and staff procedures. Altogether, the participation of the 1st Provisional Marine Brigade was an important factor in stopping the NKPA invasion in August 1950 and punishing the invaders so severely that they were ripe for a crushing defeat the following month. The Marines, moreover, did a great deal to restore the national pride of countrymen who had been hurt and bewildered by the outcome of the first month’s operations.
