Need Help with Free Upkeep Units

[battle4545]

How do you get free upkeep units, i heard that it is possible with some types of construction but then some say its bugged and that does not happen too.
are any of you using free upkeep units and how ???? thanks

You only get free upkeep at your cities, not castle, and only with militia units and ONLY IF you have the appropriate barrack level that can produce the specific unit.

Example: You have a wooden wall that can support 2 free militia unit, if you don't have the mustering hall (lvl 1 barrack, produce peasants) then putting 2 peasant units will not be free until you build the mustering hall.

That is not true. You will get free upkeep for militia units at least one level below the current city size whether you have the barracks required for it or not.
