Considerations about mercenaries.

Hiring mercenaries
Mercenaries!

Summary
Under gold payment, have a group of mercenaries that you can't directly control, only ask them to either scout, attack, or defend. If killed, they auto-regenerate. Max 20 units.

Variants

 * not very loyal (link).
 * limited time use, and everytime you call them, it costs more (link)
 * They spawn automatically in fixed time periods and fight for whoever controls their "tavern" building; a couple of taverns are spread over the map, thus mercenaries would be one specific game mode.

Advantages

 * Helpful with scouting, raiding, or defending without the need to control these units and keep track of them all the time.
 * Not regulated by population limit, thus additional military forces in the late game.

Disadvantages

 * No tactical finesse, they might go to their death or defend the wrong location.
