The European theater in World War 2 encompassed all terrain types from arctic to desert and all others except Jungle.
African military forces focused on fighting one another rather than European armies.
When? During what war or time period? For example, during WWII General Dwight D. Eisenhower was the Supreme Commander of all Allied armies in the European Theater of Operations.
During the 16th century, fighting advanced from medieval warfare to the use of firearms. Fighting could now be done from a distance with standing armies apposed hand to hand, one on one fighting styles.
Ost - East Heer -Army So the word Ostheer stands for the German armies during WWII, which were fighting on the Eastern front.
Most European countries were involved in World War 1. In Western Europe, most of the fighting took place in Belgium and France and in Eastern Europe, Turkey and Bulgaria saw a lot of fighting.
Germany... I think??
The fact that the terrain was difficult and hazardous,they could not use heavy artillery.
Railroads were destroyed by the invading Union armies, and ports were blockaded, and most of the menfolk were fighting in the army.

Nazi Germany in the European Theater of Operations, and Imperial Japan in the Pacific…
American soldiers were fighting on the European front against Germany (this front often includes those fighting in Africa) and the Pacific front against Japan.
The Axis powers (Germany and Italy) were the European powers that were fighting everyone else.
