Hummel

"Jeepers! A Hummel tank? A "bumblebee" tank? Well, I spoke too soon for that!"

--Su Ji-Hoon, Tanks in the Wind

Hummel (German: "bumblebee") is a self-propelled gun based on the Geschützwagen III/IV chassis and armed with a 15 cm howitzer. It was used by the German Wehrmacht during the Second World War from early 1943 until the end of the war, and again for the Nazi Union during World War III.
