How to defend against the weather controller in Red Alert 2

This is simple, select a unit and press the G key. When the enemy approaches, the troops will automatically track and attack. But this method is not recommended. If some troops use alert, you will need to look for it everywhere after a while. To guard the selected troops, press Ctrl + Alt on the keyboard, then click on the target that needs to be guarded, and then it will automatically guard the selected target. The advantage of this method is that the guarding troops will always follow the guarded target. Maintenance vehicles and team maintenance are most suitable for this method.
