Beck gained respect with the publication of his tactical manual, "Truppenführung". Both Beck and General Werner von Fritsch commanded the 1st Cavalry Division, in Frankfurt an der Oder prior to assuming their command positions. During his time first as Chief of the "Truppenamt" (1933–1935) and then as Chief of the General Staff (1935–1938), Beck encouraged the development of armoured forces but not to the extent that advocates of "Panzer" warfare, such as Heinz Guderian, wanted. In Beck's conception of power politics, it was crucial to have German military power restored to its pre-1919 levels, and from the latter half of 1933, he advocated a level of military spending beyond even those considered by Hitler. Once Germany was sufficiently rearmed, Beck thought that the "Reich" should wage a series of wars that would establish Germany as Europe's foremost power and place all of Central and Eastern Europe into the German sphere of influence.
