Thats where the Germans figured that the 88MM AA gun worked great as a anti tank gun. The French staged a breakthru and Rommel ordered his AA gunners to deploy as anti tank. It was the only way the attack was stopped.
Yeah. The Char B1, the Matilda, and the Soviet KV tanks all required 88 FLAK to stop them.
On Char B1 destroyed 13 Panzers before it retreated.
