I read a comment in another article from an American who thought that Western tanks were so good that they didn't need these modifications mocking Russia for having to do this for their tanks.
It's fascinating to me how these small commercial drones have changed warfare. The mighty M1 Abrams with a reputation of being invulnerable before... now exposed by a simple adult toy. No need for expensive top-down attack anti-tank missile systems... They ain't going to easily write books about it because this tactic was a complete surprise and wasn't thought up by the West. If this wasn't employed in another small regional war first, the US would've been the first victim of such an attack and would've been taken completely by surprise because this wasn't even on their radar. That's why the US is behind when it comes to drone technology.
I remember reading a book when I was younger about tank design. There was a lot of emphasis on angles because nearly all attacks on tanks then were seen from ground level. Depending on the angle, it would increase the thickness of the armor. It was very important in the calculus of tank design. Now all that is thrown out the window because of drones. In future tank design will they have to increase armor thickness from all other angles besides just the front now thus increasing the weight affecting the performance of the tank? Will these ugly bird cages now be a part of how tanks look from now on?
When I was a kid there was a Japanese anime movie I watched where the crew of a space ship crashed landed on an planet that had an ancient alien civilization on it. The only thing left working was its defense system which was launching thousands of head-sized orb swarming drones at a time. These drones exploded on impact or they would open up turning into metal razor jaws where they would clamp down on any body appendage they can grab and then explode or they would deploy a tether-like tongue to wrap around the neck pulling the head in and clamping down with it metal jaws and then exploding. The whole movie was an action-laced fight for survival. I can see that coming minus the razor jaws of course.
