27th Marines, 5th Marine Division
In case you don't already have it, Byron Earl Fisher's commissioned service number is 030288. This may assist in locating records. (I posted this earlier today but, for some reason, it didn't register. Webmaster must be as chintzy as some of his contributors).
(I'm not chintzy. Well, not excessively. I'm Morman and I grew up in a Jewish neighborhood. In the dictionary under "cheap" it says, "see Ol' Uncle Bob".)
