Every single modern, "traditional" war, like Ukraine boogaloo, causes insane material and manpower losses to both sides. This forces countries to start saving on anything they can, while maintaining minimum viable defensive and offensive capabilities.

The current estimate on the Eastern front for example is 400-4000 dead men a week.

That's not quite right either. Sets like pic related are very flexible and ergonomic, but they do cost a shitton of money.
