8.8 cm Flak 18 on SdKfz 8

The 8.8 cm Flak 18 (Sfl.) auf Zugkraftwagen 12t (Sd.Kfz. 8), also known as the Bunkerflak or Bufla, was a German Wehrmacht half-track self-propelled gun developed before World War II and used in the first half of the war. It was used during the Invasion of Poland but is best known for its use during the Battle of France, where it was the only German self-propelled gun capable of destroying the heavier Allied tanks such as the French Char B1 and the British Matilda II. Remaining vehicles were used on the Eastern Front. The last Bufla was destroyed in 1943.
