When are you authorized to wear two of the same ribbon?

Thanks ! I never knew that !

Is one with Valor? Did they have 26 of the same award? Forgive my math possibly

A relative of mine was an Army Officer who spent 3- tours in Vietnam once told me that medals and ribbons were for the enlisted, not the officer corps. Never cared much for him.

Generally: ;For instance, I earned the National Defense Medal three (3) times during my career.
1st. Viet Nam 1965-1968 USN/2nd. Desert Shield Desert Storm 1991/3rd.Enduring Freedom 2001 NVANG (1979-2005) CCAF/Senior Enlisted Advisor- E-8/SMSGT
only one (1) ribbon, but, 2 devices: showing 3 times awarded:
I have not seen 2 of the same ribbons worn at same time, on any Class A uniform.

I never came across that . But to me , he should have 1 ribbon with appropriate clusters that add to his awards .

Thanks for the add in. Looks like a good s ite to gleen lots of good info

Yes. The Viet Namese Presidential Unit Citation is the Viet Namese Cross of Gallantry Ribbon with a gold laurel leaf frame and a bronze leaf device. The Viet Namese Cross of Gallantry, a personal award, uses the same ribbon but with no frame and a silver, or gold star or a bronze or gold leaf device to indicate what level (regiment, division, corps or army) made the award. Both these awards were commonly awarded to U.S. units and personnel. I wore both on my Marine uniform since 1968, in accordance with the Navy/Marine Corps Awards Manual.
Unit awards using a personal decoration ribbon but with frame and the use of different devices to indicate the level of award is common in France and its former colonies. Of note the Viet Namese Cross of Gallantry ribbon is a clone of the French Quoix de Guerrero ribbon.

I have currently the same problem then...I have tried to use rack builder to do my AAM. Nine awards for service and two mobilization awards.

no
