Group Mobile 100 was finished. Less than half of its more than 3,000 men made it from An Khe to Pleiku. Virtually all its vehicles and equipment were destroyed or captured. In five days of fighting the Korea Regiment had suffered more casualties than in two years of fighting in Korea.
Damn, the Korea battalion suffered more casualities in 5 days fighting the Viet Minh than they did with 2 years fighting in the Korean War.
