I 'spose the choices would be mission based,
As a "ruck" mission, DA/SR, etc, I would do the prc-74
As a support mission, like a base commo or something I'd take the FRC-93, or KWM-2A,
As a pure UW I would take the 109 for interchangeability of components to thwart any SIGINT/Operator finger printing by OPFOR.
All great radios for "their day", I still would love to have one each of them...
I'd have to brush up on the 'ol code though
Nice thread BTW
