We did have the little PRR come on issue in late 2005 and it was issued to each combat soldier in '06, we would run a section net, with a PL channel loaded for emergencies. The Section commander had his PRR tied to the little PRC521with dual PTT switches for commanding the section and bothering the PL commander. It worked suprisingly well.

Having everyone tied in to a small net makes C&C so much smoother.
