What exactly is Blitzkrieg?
Only the Wehrmacht and Li Lin could probably clarify this question. Even Roland, deeply knowledgeable about the ins and outs of Alfheim, would likely find it quite a challenge to systematically expound on this issue.
Blitzkrieg is a large formation deep breakthrough operation, mechanized warfare, mobile warfare, and annihilation warfare. It's a comprehensive strategic and tactical concept at its core "rapid maneuverability." In a sense, any annihilation battle centered around the rapid mobility of large formations can be called "Blitzkrieg." For example, the Soviet Union's large formation deep operations, the Warsaw Pact Group's surprise attack on Czechoslovakia during the "Prague Spring," and the USA military's "Desert Storm" operation in the early 1990s can all be considered different versions of Blitzkrieg.
