Unit Commands
During the command phase players can change the active command queue of each unit they control.
Factories (e.g. vehicle plants), towers, laboratories and mobile units accept commands to execute during the following phases.
Most structures and mobile units allow queueing up to 16 commands each.
Commands are typically issued via their hexagonal control buttons.
Movement and attack commands may be issued by right-clicking at hostile units or terrain locations.
This feature is available to mobile units and towers.
Use the shift key to queue up commands.
With the exception of very few commands (e.g. placing a unit that has been completed by a vehicle plant), all commands are queued rather than executed immediately.
Units with empty command queues may end up doing nothing at all.
Where appropriate, these units will be considered idle.
Offensive units (including towers) can fill their command queue on the fly if hostile targets are within safe attacking range.
