What code in conditions to restrict radios triggers to Commander only?

[majorexperimental 3]

I want radio triggers that only should be possible for Blufor commander to use. Now I use this code: "this && leader player == player && side player == WEST" as condition but this make that all group leaders can access the radio triggers. What code to restrict to commander only? Any ideas?

Give the unit a name, Unit1 for example and use this as the condition

This && player == Unit1
