NotesThe T-37A was the world’s first massed produced amphibious tank and developed from a Vickers design tankette. It had just enough armour to stop a standard bullet and was armed with just a single machine gun. It was issued for use in a reconnaissance role, but many were used in the infantry support role. It first saw action during the Soviet 1939 invasion of Poland and many were still in use during the opening phase of Operation Barbarossa, these suffered huge losses against the well led and well equipped German spearheads.
