The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Service Cross to Captain (Infantry) Frank W. Lukas, United States Army, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving with the United States Military Advisory Group, Korea, deployed as Advisor to the 2d Battalion, 26th Republic of Korea Regiment. Captain Lukas distinguished himself by extraordinary heroism in action against enemy aggressor forces in the vicinity of Kangnung, Korea, on 6 February 1951. On that date, the 2d Battalion, 26th Republic of Korea Regiment, was given the mission of attacking an estimated three battalions of Korean communist soldiers who had held up the 2d Battalion advance for three days in the vicinity of Mosan Hill, a dominating terrain feature commanding the approaches to Kangnung. Captain Lukas, equipped with a backpack Air Force control radio, advanced with the lead company to attack the enemy. The Company was immediately placed under a heavy barrage of enemy mortar, automatic weapons and small arms fire, during which time the company commander was killed and 15 friendly soldiers wounded. Captain Lukas crawled through the enemy fire to another position within 100 years of the enemy positions, and for two hours while under heavy constant enemy small arms fire, directed devastating air strikes by friendly fighter aircraft. These planes knocked out four machine guns, two mortars, caused 50 enemy casualties and partially disorganized the enemy in the entrenchments. At the completion of the air strikes Captain Lukas again exposed himself to enemy fire, and firing a submachine gun, led the company in assaulting the enemy positions. Inspired by the daring and courage of Captain Lukas, the company assaulted the enemy position so aggressively and effectively with rifles, grenades, and submachine guns that 93 of the enemy were killed, an unknown number wounded, and 16 captured, and the remainder forced to withdraw. The capture of Mosan Hill enabled the remainder of the battalion to advance successfully on the city of Kangnung. The intrepid actions and courageous leadership of Captain Lukas reflect great credit on himself and the military service.
