[ARC5] Throat Mikes and Oxygen Masks

[DSP3]

Well, spit......  For grins, I got my old HGU-2AP helmet out (I used it 
in the early 60's), and, lo and behold, the mic is the M-10/UR so I 
guess I stand corrected.  The MBU-x series masks had this element.  
But... given the spare ones in the drawer have the 2-part wire boom, 
maybe (?) the Army used them, too?  I'll have to dig out the Army ones 
and see what's attached to the headsets.  I know they're OD in color and 
I think bigger that the M-10.  Hmmmm?
