These animated youtube videos are, I think, an excellent overview of the Eastern Front of WW2 from a tactical and strategical perspective. They show mostly the battle plans and how the formations advanced and why. It’s very detailed and the takeaway I have from it is: always do pincer attacks. Cut the enemy off from their supplies, and that way you will be able to take away whole battalions, maybe even divisions.

Conversely, protect your logistical paths. You cannot afford to let the enemy cut off your troops, and must resupply them as much as possible – during the siege of Leningrad (which lasted more than 2 years and to this day is the largest siege in the history of humanity), the Soviets used the frozen lake Lagoda to resupply the city and evacuate the civilian population. Indeed, it was frozen enough that trucks could drive on it.

There definitely needs to be a post about the siege of Leningrad on this sublemmy, because there is a ton of things we can learn from it.
