Unit information - WWII .
My grandfather was in the 2633rd Service Company O.V.H.D. which was stationed in Italy and was part of the 5th Army.My question is pretty basic.O.V.H.D stands for overhead but what does that mean? I have a complete list of all of the units that were part of the 5th Army and quite a few of them say overhead behind them. Anyone have an answer?
