Begin with the prescribed arming. While ramp start: ask your ground crew whats available and rearm. When a TGP is avaiable, you will get one. :D
I have played DevilsCross on 1.0.0.6 and begun with prescribed arming. But everthing my wingmen did, was "negative-radio-spamming". So i had no choice to ask my ground crew for TGP and 6 Mavs :)
