Troops

Troops are land based soldiers who fight in hand-to-hand combat. There are several main types of troops.

Semi-Professional
Semi-Professional troops are your standard levies. They have basic combat training and are reasonably well equipped but spend most of their time in other activities. When you call up your semi-professional troops they cost 3 gold per troop, per year. This cost is subtracted at the moment you call them up and is a way of abstracting the costs. If you keep them raised for more than a year, the costs will occur again at start of the next year.

Professional
Professional troops are household guards. They are fully trained and equipped. The cost of a professional soldier is 5 gold per year, 10 gold if they are mounted.

Sellsword
Sellswords are mercenaries. They are less reliable than household guards, but are still fully equipped and trained. The average price of a sellsword is 4 gold per year.
