Meh, i choose the route that i think will be more profitable example : i can send 2 inf. and 2 tanks at place that is 5 ipc’s and has 2 infantry on it or a territory that has 7 infantry worth 2 ipc’s and you can send 3 fighters 5 tanks and 4 infantry! hmmmmmmm which 1 like southern or northern what makes you get a better chance!
