You can either select all units of a category by clicking on the image of that unit type or you can enter the desired number to send in the field provided for that unit. In our example for the tutorial the target coordinates have already been correctly entered using the "Acquire coordinates" option. You can also manually enter coordinates or use the drop-down menu to select the coordinates of your own estates or war camps. The latter is only sensible for retrieving resources or stationing troops in the target location. The last step is to select the desired unit command. For the first tutorial task involving troop movements, the command is "Hunt humans". Note that only slavehunters can hunt humans. For future attacks or other unit commands, different unit types are better!
An overview of all troop units that are not currently in one of your settlements can be found by clicking on the "Current troop movements" icon directly to the left of the central world map icon.
Here you will see the arrival time, origin, target and unit command for each active troop unit. If you click on "Info" you will see more details such as the unit strength and the payload the units are carrying, if any.
