4. Notes

a) Radios are in Bttn HQs and above, may be in T-28 CHQs. Vehicles so equipped have frame aerials and must be pointed out if requested.
b) Infantry have no A/T grenades in 1938-39. From 1940 can have RPG-1940 A/T grenades.
c) Ba-32 not available until late 1939.
d) Three such brigades existed, each having 3 Heavy Tank Battalions, 1 Light Tank Battalion and 1 Motor Rifle Battalion. In theory 1 such brigade, along with 2 Light Tank Brigades (list R8) and a Motorised Brigade (list R10) 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 1938-1941. At least two of the brigades fought in Finland 1939-40, one with the Heavy Tank Test Company.
