2) Supply and Barracks - I am building barracks on several of my "Russian Federation Overseas Occupied Territories", just wondering if it would also be beneficial to build a supply depot as well?
2)Supply depots increase supply of a hex. I am a huge fan of supply depots becouse I like to have my territories in high supply. As for placing them with barracks, I do not remember if a hexes supply affects a units repair speed (the question has been asked and answered in the past on the forums but dont remember what the answer was).
It appears by his answer that Ruges is indicating he has not changed it from what is in the base game;
In my experience, the only thing which affects repair speed when a unit is in a barracks is the funding level of Maint and Training.
Now, if you have a unit that needs repairs and is not in a barracks, local supply level will affect it. In situations where I am deep in hostile territory, but have an airfield I will place my damaged units on the airfield. Since it generates supply they will repair faster while still deployed.
There used to be a misconception that a unit ordered to repair would repair faster while in the barracks, as opposed to one that needed repair but was reserved. I did some testing a few years ago and found that to be incorrect. They both repaired at the same rate. The advantage of using the repair command is the unit will deploy once it is repaired and if you have a rally point set for the, "front", it will then make its way to where you can use it again.
