Dear SSGT Herman Duncan, Thank you for your service as an Infantryman (ROTC Instructor.) Independence Day is approaching, and we remember your sacrifice. We remember all you who gave their all. It has been too long, and it's about time for us all to acknowledge the sacrifices of those like you who answered our nation's call. Please watch over America, it still needs your strength, courage and faithfulness. Rest in peace with the angels.

CURT CARTER, REMEMBERING AN AMERICAN HERO: Dear SSGT Herman Derl Duncan Sir,As an American, I would like to thank you for your service and for your sacrifice made on behalf of our wonderful country. The youth of today could gain much by learning of heroes such as yourself, men and women whose courage and heart can never be questioned. May God allow you to read this, and may He allow me to someday shake your hand when I get to Heaven to personally thank you. May he also allow my father to find you and shake your hand now to say thank you; for America, and for those who love you. With respect, and the best salute a civilian can muster for you, Sir.

Wanda Lunn: Sgt Duncan,I met you in 1967 when I was a teenager, when your friends son, Ronald John Ensley, Jr. paid the price in Vietnam. Almost nine months later, you paid the price also...You will never be forgotten. Feb 23, 2011.

Duncan, Herman Derl, SSG
