The infantry blue cord is a United States Army military decoration worn over the right shoulder of all infantry-qualified U.S. Army soldiers.
It is a fourragere in light blue, (dubbed "Infantry Blue" by the U.S. Army), worn under the right shoulder and under the right epaulette of a U.S. Army infantry soldier's Class A dress blue uniform jacket or Class B shirt.
The cord is composed of a series of alternating left and right half knots that are tied around a leader cord to form a "Solomon bar".
Enlisted graduates of infantry "One Station Unit Training" receive their blue cord at the "Turning Blue" ceremony held the day before their graduation from their training as infantry soldiers.
