Semper fidelis Marine
I too chose to be a Marine, retiring after 20 years service active duty. Many times I thought of you and your sacrifice. You were an inspiration to me.
Again, semper fi devil dog.
Remembering An American Hero
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
Mark, i look at your picture, and I can feel your goodness. I can not imagine the deep pain your family felt when you were killed after being in Vietnam for such a short time, or how much they still miss you. I grew up in Teton Valley, and I love the O'Brien family. God Bless and keep you.
