Whilst Germany deployed only 18 of its own tank model (A7V), they did capture hundreds of allied tanks and used them in their own regiments.
Fun Fact: so did the Russian Revolution. The Allies tried to invade and the Bolsheviks captured and reverse engineered Allied tanks, mostly copying French designs to make the T-18.
There is this a direct lineage from the French Renault FT to the T-34, which would become famous for fighting Panzers descended from the British Carden Loyd!
If I remember my history accurately, that’s because tanks were a new British secret weapon. The whole reason they’re even called tanks is because that was the code name, they referred to them as water tanks.
I think the original actual name was “landships”, but the “tanks” stuck better for some reason
