Is there any mention of two of the letters being zerox copies? Two of them sure look like it to me. Note the last "T" with the rope looking thingy hanging on its left igit in both letters.
Anyone in the US military would write the date as "09" as in 09 Sept 01. I'm born in America all and never used slashes in dates, i.e., 9/11/01. Kinda strange if you ask me.
