Draft

§ The Nationhood civic allows you to "draft" three units each turn. When you draft a unit in a city, some of the city's population is turned into a military unit.
§ 

Unit Type

§ The drafted unit is the best "standard" foot-soldier available to your civilization: in early eras this might be a swordsman, while later it might be a maceman, musketeer or infantry.
§ 

Unit Experience

§ Drafted units begin with half as much experience as a standard unit trained in the same city would receive.
§ 

Unhappiness

§ Employing the draft causes Unhappiness in the city where you drafted the unit. This unhappiness isn't permanent: it dissipates over time. Drafting the same city multiple times will increase the unhappiness duration further.
