Yes, you do. The motto is not merely to be stated, but to be lived. You did your part when called and you went where you were sent. My father was an Army infantryman in WWII (Africa, Italy, France, Belgium & Germany), and twice wounded, so I've got a warm spot in my heart for my dogface brothers. I'll tip a glass of bourbon toward Illinois, with best wishes to you and yours...
And so will I with you any time. Your father, my father-in-law, have given far more than their time (which is what I gave). I can't imagine their sacrifice even though discussing it with him. I can only hope to find a true explanation, and some final answer for the family.
Yet, to you and yours, a blessed life, a life with honor, knowing your sacrifices as duty to America. God Bless!
