[Can someone explain how to use the support?]

I solved it. I pressed 0 - 8 to bring up the communications menu. Then i just left clicked on the map!

[Can someone explain how to use the support?]

Im completely clueless about how to use the support options in the campaign.

Starforce 21. How do i use this service? How do i tell it to go anywhere? Feels like i've tried everything. Radio commands, placing markers on the map etc.

I am currently stuck in a mission and im in dire need of getting this to work. I am in the chopper but i have no idea how to get it to go anywere.

I would read the manual to find the answers myself. But i don't know any german :)

Can anyone fill me in real quick?

Thanks!
