I was talking about tanks which we are planning to buy so that they can be air dropped.....Paratroopers have to either win/survive or die. If they win, they will be relieved by other ground forces once they link up with the paratroopers. If they don't succeed in their mission, then they are either killed or captured. Or they have to be rescued by other ground forces, if possible, which means they have to survive as long as possible.
Paratroopers and ground troops have to work in tandem. Which means you can't just take a division and then fly off to Mongolia and drop them in the desert if there's no chance of a link up happening with ground troops.
