At the end of 1938 to the beginning of 1939, it was arguably the most torturous period for the German Army.
The external resource supply was cut off and the transportation system in Russia Nation was essentially paralyzed. These two debuffs drastically reduced the combat effectiveness of the German Army.
It is to be noted that most of the elite units of the German Army had already perished on the battlefield.
Currently, the main force of the German Army in terms of combat capability was not so exaggerated; it did not have a significant advantage over the main forces of other Nations.
Especially when facing the tenacious Russian army and the powerful Australasia Army, the German Army rather struggled.
Although the Russian army often suffered several times more casualties than the Germans, they were indeed the force the Germans least wanted to face, aside from the Australasia Army.
