On top of that, Russia should be the gold standard of SHORAD in both quality and quantity, yet drones and UAVs continue to penetrate defenses with regularity. Ukraine, who inherited one of the best SHORAD forces from the Soviet Union, saw these forces depleted or decimated by UAVs, either by causing them to expend missiles against Gerans, or have AD units, from Strelas to S-300s, taken out by Lancets.
Yes, Russian's ground-based air defense is tier-one, but their air force is tier-two at best. Their number of AWACs, ELINTs, aerial jammers and other combat support aircrafts is pathetic and they don't have EA-18G equivalent. In another word Russian air force can't provide protection to the ground force at all.
That's not the case with NATO or Chinese forces.
