“What is the difference between 1945 and 2020 according to their book?”
Normally in the world of 2020, one force would achieve air superiority, with precision munitions, which would in large part negate the need for the type of fighting we are seeing now. Especially if one of the forces involved is a so-called “super power”.
Who said it is not the case? There are obvious limits to all of the above of course.
“... one force would achieve air superiority ...”
Well, kinda, they both have air superiority — neither can fly.
The use of civilian-type drones for artillery spotting has been a boost to both sides. A drone can stand off and help sight in artillery fire, and when you have lots to call on, it’s devastating.
We are used to air superiority ruling the day. But here, a simple eye-in-the-sky gives front line troops the ability to direct fire without exposure, and they don’t have to wait for somebody half a world away to clear it.
Both sides are shooting down the other’s drones. But the Russians don’t need a Predator or similar expensive type, just a flying camera that’s less than #1,000 on eBay.
