They were already in the works. It was never a snap decision to add it because “US mains cried”.
The fact that they specifically mention that the US Block 15 was in the works and that it might come in the update at 15:38 indicates that.
I should have worded it differently, but the old “Gaijin only added the US Block 15 ADF because of US mains whining” is just bullshit. If that was the case they wouldn’t have already mentioned the US ADF possibly coming before we even got access to the dev server.
Probably in RL (past). After June '40 Germany took over the whole french inventory, except the navy. It also used every bit of it. The tanks, trucks, hotchkiss machine guns, artillery pieces, planes…everything.
Other games like Steeldivision reflect that. There you might select all these french units for German division layouts.
In WT its not possible. Germany never gets anything back. Its just a oneway ticket with Germany on the suffering end.
