How Cargo aircrafts effect logistics in the campaign?

[JOKER_duke]

Dear Friends!

When i add a squadron of C-17, the HQ then Automatically send C-17s to other airbases for transporting.

So is this truly effective for distributing supplies or just an eye candy in the campaign?

I post the same question in the General Discussion board but nobody answers. So i am appreciate if i can get a reply here. Thanks!
