It is generally recognized that the German high ranking officer of the Second World War [WW2] was highly adept and displayed considerable proficiency when:
1. Employing with effectiveness in combat ad hoc units.
2. Containing and defeating an enemy breakthrough offensive [a rupture of defenses].
That German WW2 combat commander most skilled at creating and using with effectiveness ad hoc units in combat Erich von dem Bach-Zelewski.
Erich von dem Bach-Zelewski.
"General of the Higher SS and Police Leader Corps, responsible for anti-partisan warfare on the Eastern Front during World War Two."
"Highly regarded by Hitler for his brutality and improvisational skills – he was able to conjure armies out of very unpromising material, he ended the war as an Army Commander."
Ad hoc units for instance - - a division [a combat division in name only, in actuality much reduced in size] consisting of perhaps a regimental sized detachment of trained and experienced infantry bolstered by a battalion each of: Hitler Youth, Luftwaffe and Kriegsmarine comb-outs, Volksturm over-age soldiers, and a company [battery] each of armor and artillery!
That German military commander most adept and proficient at containing and subsequently defeating an enemy breakthrough offensive Walther Model. Model the archetype of the skilled combat commander on the defensive working almost miracles on the battlefield albeit in a harsh and unremitting manner.
"Otto Moritz Walter Model . . . was a German general and later field marshal during World War II. He is noted for his defensive battles . . . best known as a practitioner of defensive warfare."
"[he was] repeatedly tasked him with retrieving desperate situations"
Contain the breakthrough, plug the rupture in the defensive lines, destroy the attacking enemy force, stabilize the situation, bring order out of chaos. For this Model is the epitome without equal during WW2.
Bach-Zelewskid and Model both fervent followers of the fascist cause, devoted unto the end. Bach-Zelewski also a commander of Einsatzgruppen on the Eastern Front during WW2, responsible for the deaths of many hundreds of thousands of Red Army commissars, Jews and partisans. WAS NOT punished post-war, his testimony in return for immunity from prosecution.
