Good point about the UAVs.
Didn't think about that while writing, though I'm usually an UAV guy ...
But I would not neccessarily integrate an UAV into a company, only give it a data receiver station. Assuming that we talk foot soldiers here only micro/mini-UAVs come into question - they are nice and developing fast, but their capabilities are quite limited so far. And I wouldn't integrate too many non-shooters in too low echelons, also because of ECM/ECCM issues and advanced homing-on-emitter ammo. Of course in the future we're not only talking UAVs, but also UGVs. UAV/UGVs I'd put higher up (battalion level plus), together with ISR assets, like SIGINT. And once they reach autonomy they will filter down through all the echelons, but I'd start with them at battalion level.


Guided missiles on platoon level is not realistic, too expensive. Esp since they are needed only for certain missions. And if organized in fire crews on a higher level they can be distributed downwards if needed, anyways.
Precision-attack capability for squad/platoon level could be realized by targeting capability for PGMMs.


Why only 60mm mortars? The Wehrmacht had quite good experience with the 3-men crew served sGrW34. A lot more punch than 60mm, I think it justifies the higher weight/less rounds ammo. Esp when combined with a MGL at platoon level. To save weapons weight use a short barrel. No need to reach out to 5000M+ in my opinion. How do you ID targets so far out?
(Even though I have to admit that the follow-on to sGrW34, Granatwerfer 37, was designed to reach out to 4500m+; but the reason for that might be non-tactical).


That brings up another question: So squads are seldom fighting beyond 200m. Meaning platoons neither. What should then be the reach of an infantry company? I think 2500 to 3000m is realistic. Opinion?
