Here's an idea for a much more practical innovation that will have implications the world over.
NORINCO or the Russians should make a longer-range precision-guided version of RPG-7 (and similar model) ammunition.
Rather than relying on the skill of the individual gunner over open sights, with the use of a guided round 1st round, 1st shot kills could almost be assured.
Imagine the implications of this development:
Small groups of soldiers the world over equipped with RPG's would be able to hit rapidly-moving tanks, armored vehicles and even low-flying aircraft within the lethal range consistenly - making it far more difficult and costly for the 'imperial' powers to wage unjust wars against them!
Casualties for them would probably go up by at least a factor of 10! - until they learned to keep their distance.
Driving around at high speed within hostile zones would be suicidal.
It would effectively end 'hearts-and-minds' operations within enemy-controlled territories.
They would be unable to send mercenary soldiers into these areas - Blackwater's operations would end.
Theft and exploitation of a regions natural resources would be almost impossible to undertake without prohibitive losses.
This is one innovation that is crying out for fulfillment.
