Truppenführung
Truppenführung ("Handling of Combined-Arms Formations") was a German Army field-manual published in two parts as Heeresdienstvorschrift 300: Part 1, promulgated in 1933, and Part 2 in 1934. The original German-language text, which is notable for its clarity, was prepared by a group led by Colonel General Ludwig Beck (1880–1944) (who was later executed by the Nazi regime for his part in the 1944 plot against Hitler).
