Gregory's Server@cstross side comment: as Trent has pointed out, drones are particularly effective against Russia, although drones do mean quite a big shift in cheap / high volume firepower.
Also: the US mil/ind complex struggles with drones because they disrupt BAU “big iron” spending - hence the //extreme reticence to support UKR// and thereby evidence a changed requirement for defence spending.
@grievousangel The mil/ind opposition is prone to shift: consider if you will the contrast between the B-21 and other gold-plated bomber programs and the RAPID DRAGON system which turns any old tactical transport plane into a cruise missile carrier: https://en.wikipedia.org/wiki/Rapid_Dragon_(missile_system)
There's a tension between keeping the pork barrel full of prime cuts and getting the job done by bulk buying at wholesale prices.
