I am building a Chieftain ARRV Mk7 and after a long and challenging build I have come to the point where I have to do something about the crew headgear and mic. I don't know what the official term is for this equipment. The Tamiya donor kit has a plastic blob that the commander holds in his hand, what does it actually look like and how is this connected to the headphones or apparatus in the vehicle. Then there is some device on the chest of each crew member, is this part of the gear, if so, which colour should it be?
Googling for "chieftain headgear" gave me a lot of native American pctures...

cheers,
Matthijs
