Re: Forrest was S. Sgt 330 Inf 75 Div
It says he was in the 330th Infantry Regiment which was one of the infantry regiments of the 75th Division of the US Army.
There is a problem. The 330th infantry Regiment was part of the 83rd Division which landed at Normandy in June 1944. The 75th Division didn't enter the war till December 1944 when it was committed to the Battle of the Bulge. Both units saw plenty of fighting.
Since he was a Staff Sargent he must have been in the army for a good long time.
Here's a web site that gives a brief history of what every army division did in the war.
