I'll add my voice. Just the fact that you are willing to put yourself between your "beloved home and the war's desolation" (to try and quote Heinlein) is enough to deserve the thanks of every American. (And the same for every other country and their servicemen.) Just because you were not called upon to face the fire does not mean that your dedication and service are any less meaningful.
My heartfelt thanks to those who serve or have served, in peace or war, in whatever capacity.
