The final image you will see of a loved and respected brother or sister will be a panicked, screaming US soldier trying to outrun an explosive toy. No doubt about it.

I'd assume -- expect -- that the US is gonna have pretty solid counter-low-end-UAS hardware down the line, but yeah, broader picture, there's gonna be some kind of weapon that'll kill people in use, and nothing's gonna afford invincibility.

Probably somewhere in the conflict you've got someone using stuff like punji sticks. Might not be the state of the art, but still can kill.
