NotesThe T-40 was a light amphibious tank which was developed to replace the T-37. It was designed as a reconnaissance vehicle which could easily ford water obstacles. It only mounted a 12.7mm heavy machine gun plus a 7.62mm coaxial machine gun and this meant that it had no real offensive fire power. It was only built in small numbers and issued to reconnaissance units, it saw extensive action in 1941 and many were lost in the battles to defend the Russian capital.
