My previous reply made me think about war portrayal in fiction a bit. I know I'm very much an amateur here, but I'm thinking of "realistic portrayal of the brutal realities of war". I'm just thinking aloud here...
- WW1 trench warfare is one type of brutal war, and was new at the time. This does a good job. Parts of Tanya the evil take place in a similar trench warfare zone.
- Trench warfare reappeared in large scale in the current Ukrainian war. We're not hearing as much about probably largely because the earlier Ukrainian trench defensive lines have now been overrun. Now, it's more mobile warfare.
- US has typically engaged in aerial warfare. Intense bombing.
- Current Gaza warfare is a mix of intense aerial bombardment destroying on the order of 80% of structures with population being shifted around into various camps. In addition to that, tunnelling and fixed pockets of fighters has played a major part.
- Drone warfare has played a greatly expanded role in both Ukraine and middle east wars.
- If we go back in time, we could look at what prolonged siege warfare (of towns/castles) was like. > Starvation, etc.
- Obliterating conquering warfare. Where an invading/conquering army lays waste, destroys villages, rapes and kills civilians. Plenty of that in history.
- "Civilized" warfare: Fought only between armies, not in cities, and for limited periods of time. (Because otherwise, the valuable resource of "people farming the land and producing stuff" would be destroyed.)
