Hitler did not fight on any front in WWII, but Nazis fought on the Eastern front,(Russia) and western front. In WW I Hitler fought on the western front, but as I remember it he was not a combat vet, he ran messages.

Ost - East

Heer -Army

So the word Ostheer stands for the German armies during WWII, which were fighting on the Eastern front.

The Italian front was located along the Venetian plane and the Eastern Alps. This location was used to determine troop setup during World War I and was changed during WWII.
