Pages 37-38 of PS 721 (Dec '12) told you how to build a forward area refueling point (FARP) helmet with a list of all the parts. Here's the link to the article:
However, the microphone headset, NSN 5965-01-204- 8505, that’s listed comes with a mouthpiece that straps over your mouth. For those flying Apache E-model aircraft, the headset mouthpiece can move around and get in the way while crawling under and around the aircraft during re-arming.
There is an alternative microphone headset that aviators can use instead. It comes with NSN 5965-01-390-9240.
TYPE P/N M87819/1-01
Order the microphone headset that works best for you during FARP operations.
