Heinz Guderian (1888-1954) was a German General officer who, drawing on the writings of Liddell hart and other theorists between the world wars, was instrumental in creating bold new military tactics to quickly achieve victory on the battlefield.

Most important in these new tactics was the concept of the "schwerpunkt" or attack point, to which fast-moving attacking forces would be concentrated to achieve a decisive breakthrough. Soon dubbed "blitzkrieg" (lightning war) by an American reporter, Guderian summarized the tactics of blitzkrieg as the way to get the mobile and motorized armored divisions to work together and support each other in order to achieve decisive success.

"In this year (1929) I became convinced that tanks working on their own or in conjunction with infantry could never achieve decisive importance. My historical studies; the exercises carried out in England and our own experience with mock-ups had persuaded me that the tanks would never be able to produce their full effect until weapons on whose support they must inevitably rely were brought up to their standard of speed and of cross-country performance.

In such formation of all arms, the tanks must play primary role, the other weapons being subordinated to the requirements of the armor. It would be wrong to include tanks in infantry divisions: what was needed were armored divisions which would include all the supporting arms needed to fight with full effect." from "Panzer Leader" by Guderian
