Quad bikes in a mechanized assault tells you a lot about where Russia is at right now. People keep talking like Moscow has some endless armored fist waiting to roll west, but then you look at places like Kupyansk and it's MT-LBs plus guys buzzing forward on ATVs into drones and artillery. That's not a modern army in good shape, that's a force burning through men and whatever moves. Credit to the Ukrainians for turning those attacks into scrap. The frustrating part is the West still acts like sending ammo and air defense on time is some huge debate club exercise. Either help them win, or admit you're managing a war on purpose.
