Re: Divided Skies: "Everyman Gear"? (Need suggestions.)
One thing I don't think you've mentioned: Cybernetics.
The "Black Box" download need not go to only one receiver. In addition to the PDA, send it to a tab on the skin on the back of the neck - as well as a download point, this could serve as high-tech "dogtags".
Radios don't need to be in a helmet if they're in your head...and any damage that takes you off the net will kill you (no "he might still be alive!" arguments). Likewise Optic replacements give the soldier IR, flash protection and Lowlight capability, plus the capacity to use a frequency-hopping laser targetter (I see the dot, but you don't) and even an inbuilt range finder and artillery designation capability.
Make your weapons and high-tech gear interface-only and low-tech enemies can't use it (and high-tech ones will have to modify for compatibility). Cybernetic limbs wouldn't be given out willy-nilly, but might be a better option for a soldier than cloned replacements, especially if the Army promises replacement with cloned parts upon discharge (which is likely - they wouldn't want military cybertech out in the civilian society).
Of course, this sort of stuff is expensive. Eye replacement would be done only for elite soldiers. But in built interfaces and radios could be grown in situ with an injection of nanobots and a high-metal diet.
Oh, and if you have man-carried UAVs, forget grenades. Just send a very small UAV wth an explosive charge.
