A silver oak leaf is the rank insignia for officers in the U.S. military in the O-5 paygrade, which is designated Lieutenant Colonel in the Army, Air Force, and Marines and Commander in the Navy. To avoid confusion, different abbreviations are used for Lieutenant Colonel: LTC for Army, LtCol for Marines, and Lt Col for the Air Force.

All four branches authorize the wear of tie tacks or tie clasps featuring insignia of rank with their long ties. Army regulations have nothing to say regarding the positioning of the clasp or tie tack, but the other services do provide guidance on the matter. Navy regulations state the clasp or tack is to be worn horizontally one inch below tie’s center, which should result in it not being visible when a uniform jacket is buttoned. The Air Force rules are similar—the device should be centered between the bottom of the tie know and the bottom tip of the tie. Marine Corps regulations are fairly specific, stating that the tack/clasp is worn horizontally at a point that’s midway between the third and fourth buttons from the top of the shirt.

Although the Coast Guard is under the authority of the Department of Homeland Defense, it is one of the Armed Forces of the United States and its officers are classified using the DoD pay grade system, so its O-5 Commanders are represented by the same silver oak leaf in the other four branches. The Coast Guard’s uniform regulations stipulate that tie tacks and clasps are to be aligned with the center of the chest pocket of the Service uniform shirt, and like in the Navy the tack or clasp must not be visible when worn with the Service Dress Blue coat.
