The Tankette's Late Successor

Tank building worldwide made a radical jump forward in the second half of the 1930s and kept up the pace until the start of WWII. The stagnation of the early 30s led to many nations starting the modernization race on even footing. Some nations managed to create designs with great potential, others fell behind. Italy was among the latter. One of the characteristic designs of this era was the L6-40 light tank, which combined progressive design elements with downright archaic solutions.

Plain and Simple

"To Molotov
London
Enciphered

I have received your enciphered message. There are no big changes on the front lines. There are battles around Barvenkovo and Izyum. The Germans have six tank divisions here. Izyum is in our hands, the Germans have Barvenkovo. Our offensive near Kharkov has stalled. The Kerch peninsula had to be abandoned. On other fronts everything is the same, we're gathering our forces, building reserves. We desperately need fighters and tanks. Tell the British to send more fighters and tanks, especially Valentines.

Stalin

May 23rd, 1942"
