>In case of the events in WWII the doing is very half-assed and feels more like a coincidental thing, they went with the grain.

Yes. Eastern campaign was shitty planned by Germans, they relied on initial rush and were euphoric about easy European conquest. Big and old enemy - France - gone to nowhere in year, who else could stop glorious Aryan people? So, Germans really thought that it will be relatively easy thing, and no one expected what happened next.

>What I read that mostly Ukros and other "minorities" sided with the Germans.

It is pretty complex question.

First - most of "minorities" (considering Ukrainians as minority is pretty wide speculation though) had some nationalist anti-soviet forces already. Such forces in Russian mainland were nonexistent, because half of them emigrated in civil war, and others were crushed in 20s (Tukhachevsky even used chemical weapons against Tambov peasants). National republics, especially far from center, were less controlled and had serious anti-Soviet and anti-Russian sentiment. "New lands" like Western Ukraine or Baltic, even had armed resistance, so it is obvious that these people would be overrepresented at German side.

Second - USSR ordered mobilization early, and most young people who can fight already were in Soviet army. Military propaganda did a good thing and they wouldn't want to support Germany in the war (except for people like Chechens as I wrote before). Many people and industries were evacuated to Siberia (many known modern industry companies like Uralvagonzavod started as this).

Third - post-war historiography on USSR side openly talked about evil nazi-collaborators from minorities, but was almost silent about RLA and Russian forces, it was a taboo (and often remains today). There is even no official count of these people. One source (from wiki) says that biggest part of pro-German armed forces (400k people) were Russians, next (250k) were Ukrainians, other groups were smaller. It still pretty shady thing because being member of pro-German forces was criminal offence, people were jailed and sometimes executed long after war for this. No one from these people want to say about war past.

Main problem was bad planning from German side and shortage of time. Most of territories were occupied for maximum 1-1.5 years, and Germans had nor time nor resources to build proper system for military recruiting in situation when heavy warfare happens in few hundreds kilometers away.
