Marine Sgt. Maj. John Canley’s astounding heroism in Vietnam 50 years ago speaks for itself, so loudly that Wednesday he’ll be awarded the Medal of Honor by President Donald Trump at a White House ceremony.

Sgt. Maj. Canley took command of the undermanned Company A, First Battalion, First Marines despite shrapnel wounds during the bloody battle of Hue in 1968. How he set up a base while caught in a “deadly crossfire,” drew fire by darting into the open so his Marines could seize a building and carried wounded Marines to safety while exposing himself to the enemy.

“Then-Gunnery Sergeant Canley’s heroic actions saved the lives of his teammates,” according to a White House statement.
