If we aren't paying any unit support currently, then keep updating our maps there lurking along Piffle's border. If we are paying unit support, then try to get it a transport home, and if that isn't possible, disband it.What do we do with our Camel Archer?
Regarding Loco, we may have come to a point where sending them more troops will slow Epsilon's advance so little, that keeping those troops for our own defense is better.
