Russia and Ukraine

[Thumpalumpacus]

Tracked guns and technicals are one thing russia and ukraine both do well.  If they have to move those that's fewer of them out there mowing down medics.

SPAAGs are cost-effective against drones, but you'd better build one hell of a lot of hulls to defend airbases spread out around a country 8,000 miles across. That's the redecision here, because it's not like Russia can build a lot of even lightly-armored vehicles with good sensors.
