Glad hearing about ANY friend pretty-much: "Acing" ANY test.
Still, and in no way whatsoever disparaging helpful Boats being of assistance, I was truly
surprised with your having 42 months (as military recognized) in a Combat Area,............
even having to ask ANYONE about hell.
I figure you already recognized & survived many aspects of so-called: "Hell" first hand,...
and for quite some time to-boot.
Stay Well, Stay Lucky & keep: "Acing" those tests.
