This command will halt the unit(s) that you currently have selected. Halting units makes them enter exile mode and return to safer land.

This is the only way to use the halt console command. To select a unit, click on it, then run this command - it will then enter halt mode and start to exile to safer land. Note that unlike the exile command, this command isn't a toggle command - running it again with a halting unit selected won't stop that unit from exiling.
