Some of the pundits told us that the Ukrainians would roll over.
They implied that Ukrainians would not fight for their 700 square-foot cabins, 1/2 acre garden plots and $60 a month pensions.
They told us that the Ukrainians had a few, obsolete Soviet fighters and that Russians would quickly dominate the airspace.
They told us that small-arms were an after-thought on the modern battlefield.
Review of what the pundits "knew"
Be it ever so humble, home is what you defend. If the only thing keeping you and your wife fed is a garden and a Ukrainian state pension, then those are worth fighting for.*
Manpads are cost effective. They cannot hit a fighter at Mach 1.5 at 40,000 feet but those planes have to land sometime. Strafing runs bring them into manpad range.
Without plentiful, clean fuel, tanks and planes are not very useful.
Tanks don't have much armor on the top of the turret. A cheap UAV (aka, drone) can drop a shaped charge on the top of a tank turret. An expensive one can hit it with a missile. Sympathetic detonation of the cannon rounds will obliterate the infantry within 30 yards of the tank.
Molotov cocktails can make tank crews very uncomfortable. They still need air to breath.
The Russian army is filled with civilians who are conscripted for a two-year hitch. They are not career military people. Their homes are not being threatened. They want to go through the motions and muster-out with all their body parts working. Getting shot by a little-old-lady in the gonads is not on their agenda.
*If there is one thing I hope our "elites" take away from this conflict it is that I have different values and a different way of seeing things than they do. They might look at my 50 year-old, 1400 square-foot house and scoff because it is assessed at 10% of what their dwelling is assessed for.
They see an investment. I see my home. Our vastly different perspectives makes me unpredictable because our values map in different directions. Clockwise isomers don't behave the same way in the body as isomers with tails that corkscrew in the counterclockwise direction.
