One of the thing that irked me about the original HoIs is the instant teleportation of leaders.
Sure it made for some humor with the AARs, but to make it more realistic Generals should have travel time much like strategic deployment before they arrive at the unit.
Now it should be way faster than your standard ground unit can move (you can a single guy by plane after all), but it still shouldn't be instant. You could also take into account their interception if you don't have air or naval superiority through the area you're sending them too.
It should really be done by distance from capital and then back again unless you transfer them to another unit or HQ.
