4. Notes

a) Radios are in Bttn HQs and above.
b) Infantry have no A/T grenades in 1938-39. From 1940 can have RPG-1940 A/T grenades. In 1941 can add one PTRD41 per platoon.
c) Ba-32 not available until late 1939.
d) The brigade has 3 Motor Rifle Battalions. In theory 1 such brigade, along with a Heavy Tank Brigade (list R9) and 2 Light Tank Brigades (list R8) formed the Mechanised Corps. In practice the brigades acted independently, and from November 1939 the Corps were disbanded, although some were still in existence in July 1941. Can use Corps and Army Support from List R18 throughout 1938-41.
