The Russian airforce has a severe shortage of smart and guided munitions. That's why they failed to gain the air dominance they should have had in the first few days of the war. Trying to destroy bridges with "dumb" bombs is hard to do, especially when your enemy's anti-air defences are still relatively intact.This has flummoxed me a little. I mean the russian air force is nothing to sneeze at and they're ALL about the bombing and you'd THINK they'd have little trouble knocking out a few bridges and crossing areas, but it seems like they can't even slow the ukraines down. I get that there's a decent amount of forward anti aircraft missile systems and such but still.
