WHO WILL OPERATE TANKS SENT TO ZELENSKY?

It takes at least a year to be trained.

Driving a tank on the battlefield is not like shooting a pistol on the firing range.

So:

1. NATO Nazi Ukes have already been trained;
2. or military personnel from the country the tanks come from will operate them.

Option 1 implies foreknowledge.

Option 2 implies American, German and British Army will operate on the frontline.

A third option is that the intention is to continue the war for at least a year until the NATO Nazi Ukes can operate the tanks.
