Question about the "depends on unit" parameter.

[Tarres]

I would like to make the EWR radars to work only with a PBU and a generator attached, a sort of EWR site.

 

I´m trying to use the "depends on unit parameter" like in the SAM sites.

For example, I´ve been able to make a 55D launcher dependent of the existence a 55C launcher like in the real world.

 

But for the EWR, I´ve been unable to make the 55G6, for example, to work only with a PBU attached to the group.

 

Any ideas?

 

Thanks in advance.
