Well, I have another question, if anyone can answer this too:
There are few civics which give +1 military support cost.
Many may not know this so I'll explain what I could gather about this mechanic:
There are 2 types of support cost, Unit Support cost and Military Unit Support cost.
The Unit Support cost follows this: There is a number of
free units based on difficulty and your total population. You may get events or civics which give you free units, that add to this value. All the units pass this value start costing 1 gold every turn (if you don't play on deity there is also a handicap which reduces this cost in %, e.g. in easier difficulties you may cut in half this additional cost).
This means for every unit (any unit, including GPs, GGens, workers, settlers, land units, ships, airplanes, etc.) you have above the limit of free units is counted and 1 gold is added to the expenses of your empire.
The military unit support cost works differently. It has the same mechanic of a number of free units, in this case
free military units, which don't count toward the expenses. Any military unit (which doesn't include non military units) above this minimum is counted and gives an extra 1 gold cost per unit (again with easier difficulties' handicap) to your expenses.
But this only is active (at least in vanilla BtS, and in LoR too) if you have a civic which has the
+1 military unit support cost. Even when this tab in the Financial advisor says: Military Support Cost for 80 units (free support for 40) and you don't have the +1 military unit support cost civic option, this tab will be totalizing 0
expense to you. The numbers are just there because they are always calculated, but only taken in effect if you have the civic option enabled.
Which makes me think Monarchy (which has +1
support cost for military units) surely benefits a lot from Standing Army (which gives + a lot of free military units). But when you are not using any civic with this (which I think are only Monarchy, Paradise and Pacifism), the bonus from Standing Army seems useless, and you would surely opt for another military option.
Or, and here the question finally comes: There are special units which give extra
support cost (e.g. Tank). As I never reached as late as the first unit of this kind in the game I'm not sure, so that's why I ask:
Those units which have the extra support cost, this cost is added to the Military Unit Support Cost or not? So if I use Standing Army, will the + a lot free military units be filled with this extra unit cost?
So if I use Standing Army and no +1 military unit support cost civics, my Tanks will only start costing when the total extra I have to pay for them exceeds the limit of free military units given by Standing Army and other factors?
I know there are three questions, but it's actually only one, I just wanted to be sure you understand my question.
Because if this extra
cost is added separately, in a way you can't counter it, Standing Army and other + free military units options are useless if you don't use a civic which gives +1
Military unit support cost.
