This horrified the army, with its traditions going back to Frederick the Great. The army officer corps viewed the SA as an "undisciplined mob" of "brawling" street thugs, and was also concerned by the pervasiveness of "corrupt morals" within the ranks of the SA. Reports of a huge cache of weapons in the hands of SA members caused additional concern to the army leadership. Unsurprisingly, the officer corps opposed Röhm's proposal. They insisted that discipline and honor would vanish if the SA gained control, but Röhm and the SA would settle for nothing less. In addition the army leadership was eager to co-operate with Hitler given his plan of re-armament and expansion of the established professional military forces.
