I think the poster's point is that FPV drones & accurate/advanced shells mean that you get all the downsides of WW1 trenches and no-man's land, PLUS new downsides of trenches not helping so you're constantly under threat of death no matter where you are. Plus: the more people huddle together the better the target they are, so you get to hide in small groups (or solo) in the hopes that the economics of killing just you doesn't pencil out and the drones will kill someone else while _they're_ sleeping, instead of you.

If you're looking for more reading maybe start with WW1 trenches, then look for YouTube videos about Ukraine drone usage? The drone stuff may be too new for lots of writing about it, but you'll get an oblique view of it by looking at how the Russians put those roll cages / turtle shells over their tanks, etc.

If you find anything and wanted to share it that would be interesting (if morbid)!

I don't know about places to read more about it, but if you want to be psychologically damaged yourself without even being a participant there is a lot of drone footage from the Ukraine war floating around on the internet.

These clips highlight lots of incredibly disturbing events like Russian soldiers having exploding drones blow up close enough to them to cause eventually-fatal injuries without actually killing them, forcing them to kill themselves (and in some cases, their friends) with their own guns.

Its horrific to see on a human level regardless of the political circumstances of the war and who is or isn't in the right.

Written by protagonists:

"The Complete Memoirs of George Sherston" by Siegfried Sassoon. (Ignore the title, it's actually his autobiography, and you could probably skip the first book in the trilogy).

"Goodbye to all that" by Robert Graves.

Two of the best writers in the English language recounting their times in the trenches.

You can read about it, or watch https://en.wikipedia.org/wiki/Blackadder_Goes_Forth

Try Peter Cawdron's book "The Anatomy of Courage" which is a sci-fi retelling of a ww1 report.

Birdsong by Sebastian Faulks is largely about WWI, including trench warfare. And it's an excellent book, very moving & vivid.
