For the next patch the Small Garrison will resort back to being a free unit,something they were always intended to be, they were created to represent your Countries Home Guard, and as such were made up of members of a nations population, that were to old for front line duty in the Army etc. when the game was first released, most Cities were left undefended, as they contained no Garrisons for protection, and far to often, because of fog of war, Cities were being captured far to easily. Hence the sole reason for the creation of the Small Garrison, these units can't stray very far from the City they start from, they can't be transported by Rail or Sea. So as I said earlier, they will revert back to what they were created for, as free units, that cost you NOTHING! They can't be purchased,they cost zero manpower or Upkeep. They were designed to give a player peace of mind Knowing that all your Cities behind they front line had some protection.
Make it so!
