Once again, you captured the "look", Pard...
Just FYI, Manny.. "Dogface" was strictly an Infantry thing in WW2 and in Korea... They were kinda possesive of it as well... Marines later took to calling all Army troops "Doggies" (still do)...
The term Grunt came later. Initially it was believed to be an acronymn for "GRound troops-UNTrained" and applied only to replacements. Another version is that it stood fror "GRound Unit-Needs Training".
