WWI: Pigeon being released from tank
During WWI, when tanks were cornered into hopeless situations, in a desperate last ditch effort they would sometimes release a pigeon. All tanks were outfitted with normally one, sometimes two pigeons, of various breeds, specifically for this purpose. The pigeon would use unfathomable power to destroy absolutely everything around it, but often would also destroy the tank it was released from and kill its occupants in the process, which is why tank operators were so hesitant to resort to releasing their pigeons. Over 10,000 people were killed during WWI from pigeon related combat alone.
The most infamous pigeon related incident during the war was at the Third Battle of Ypres in 1917, when British colonel Reginald William Edwards released an extremely powerful Szegediner Highflier pigeon from the Mark IV tank he was operating, which had become immobilized in mud and surrounded by several German Leichter Kampfwagen I tanks. The Highfligher immediately flew up to an altitude surpassing Earth’s mesosphere, then plunged back down, diving into one of the LK I tanks and creating a massive shockwave that killed over 1,500 and injured tens of thousands of soldiers and civilians alike.
