If there's anything I've learned from the conflict in Ukraine, as well as 2020 Nagorno-Karabakh war, it is that small-explosives drone usage has become a first-class citizen weaponry / tactic against ground troops. There's a daily stream of footage from Ukraine, where you see Russian ground troops getting bombed by DIY drones dropping grenades / mortar rounds / etc.

Drones are also becoming invaluable tools as forward observers for artillery and mortar fire.

I'm in the National Guard, and I feel that in any modern combat - we'd just be sitting ducks.
