Panzer VIII Maus
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.
Science and technology in Russia
Famous Russian battle tanks include T-34, the best middle tank design of World War II, and further tanks of T-series, including the most produced tank in history, T-54/55, the first fully gas turbine tank T-80 and the most modern Russian tanks T-90 and T-14 Armata. The AK-47 and AK-74 by Mikhail Kalashnikov constitute the most widely used type of assault rifle throughout the world—so much so that more AK-type rifles have been manufactured than all other assault rifles combined. With these and other weapons Russia for a long time has been among the world's top suppliers of arms, accounting for around 30% of worldwide weapons sales and exporting weapons to about 80 countries.
