> Could a drone swarm be used to draw attention away from another incursion or are radar systems able to handle slow and low things at the same time as higher and faster objects?

Ukraine has been running this playbook the last 6 months or so. Drones in one area or direction to distract, scalp/Taurus on a high value target elsewhere. Sometimes this plays out over days.

Current air defense systems are insufficient for the new drone paradigms. They won't scale to meet the needs. We need lasers and microwave based systems.
