During a firefight on that day, in Kiến Hòa Province, Republic of Vietnam, Lang single-handedly assaulted three enemy emplacements before being seriously wounded.

[1] Specialist Lang's official Medal of Honor citation reads: For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty.

Sp4 Lang, Company A, was serving as a squad leader when his unit, on a reconnaissance-in-force mission, encountered intense fire from a well fortified enemy bunker complex.

After returning to the area of the arms cache, his squad again came under heavy enemy rocket and automatic weapons fire from 3 sides and suffered 6 casualties.

The sustained extraordinary courage and selflessness exhibited by this soldier over an extended period of time were an inspiration to his comrades and are in keeping with the highest traditions of the U.S. Army.
