The President of the United States of America takes pleasure in presenting the Silver Star to Technical Sergeant Casey R. Nix (MCSN: 304362), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Wire Chief of the Seventh Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 3 November 1950. With communications severed and subordinate units of the regiment isolated about five miles south of Sudong after the enemy had succeeded in cutting the main supply route, Technical Sergeant Nix organized and led a wire team forward in an attempt to re-establish communications with two isolated battalions. Fearlessly exposing himself to hostile machine gun and rifle fire, he continued to carry out this mission until one team member was wounded and, immediately organizing and leading a rescue party to the casualty, administered first aid before directing the evacuation of the helpless Marine. Locating an enemy machine gun position, he called for a 75-mm. recoilless rifle and, directing accurate and effective fire on the hostile emplacement, destroyed the weapon and annihilated its crew. Subsequently, he succeeded in establishing wire communications with the isolated battalions, thereby contributing materially to the success of his regiment. His courageous initiative, skilled leadership and indomitable devotion to duty reflect great credit upon Technical Sergeant Nix and the United States Naval Service.
