Not sure if someone mentioned this already.
The Americans and the Dutch are refurbishing 90 Czech T72s and giving them to Ukraine. They are not from the Czech army, it’s just a bunch of out-dated tanks that the Czech government doesn’t know what to do with. American and Dutch money will goto upgrading fire-control system, thicker armor, a new stabilization system for the 125-millimeter main gun and an uprated, 840-horsepower engine.
