Units Screen
This is simply a scrollable list of the units held within the host unit. The individual units can be selected on the list and the following commands invoked:
Clear Selected Unit Orders
This will remove the current orders from the selected unit. Useful if a unit is on sentry.
Close / Activate Selected Unit
The units screen will be closed and the selected unit will become the active unit.
Clear All Units' Orders
All units in this city will have their orders cleared.
Disband Selected Unit
The selected unit will be removed from the game.
Back To Game
This option will return you to the map screen.
Back To City Production
This option is available if the host unit is a city. The units screen will be closed and the production screen for that city will become visible.
