Drake Equation

Caltex, in order for one unit to support another unit, it has to be capable of moving into that space. So a fleet in Tri can't support an army in Bud. If Russia and Turkey are working together, then it is only a short matter of time until Austria is consumed. There isn't much anyone could do to prevent them from taking Budapest if they wanted it. I guess the only way would be if the fleet in Tri moved to the Adriatic and Italy's army in Ven moved into Tri, then in the following fall move Italy could take Tri and support Austria while Austria's fleet would take Ven. That is the only way.
