Nope. Most units will be recruited from military depots. Special units will be recruited differently. For Example to get 'The Polish Lancers' you need to be a french officer recruiting in Poland and iirc Troops won't be up gradable.Sarel said:Questions about progress are not well received here. I would recommend not asking them.
I believe recruitment and training is more or less the same as native, but special units, such as mamelukes, can be hired at military depots in cities.
