Vernichtungsgedanke, literally meaning "concept of annihilation" in German and generally taken to mean "the concept of fast annihilation of enemy forces" is a tactical doctrine dating back to Frederick the Great. It emphasizes rapid, fluid movement to unbalance an enemy, allowing the attacker to impose his will upon the defender and avoid stalemate. It relies on uncommonly rigorous training and discipline and thoroughly professional leadership. Much of Vernichtungsgedanke can be seen in Clausewitz’ classic treatise Vom Kriege (On War).
