Shipping/trucking e$$pensive as hell. For now.
deploying 15-20 of those in a theatre at ~20 million dollars per system is 300-400M worth of expense required to protect against drones that can be made for about 200 dollars right now + ~50 for an rpg warhead or 100 for an anti tank mine if you're going super low tech circa 2022 Ukraine war type stuff.
This is a required step on the way to the type of system they're going to need soon though. Something that can be mounted to existing armored vehicles, that can autonomously track and destroy targets quickly. But until then we're in the era of small drone dominance imo.
