U.S. Army tests counter-drone systems at the Mexican border.

The U.S. Army used its Falcon Peak exercise to evaluate counter-drone technologies under border conditions, Reuters reported. Officials recorded 378 drone incursions during the preceding 30 days and said commercial drones are increasingly used for surveillance by criminal organisations.

The exercise was designed to move systems beyond controlled laboratory testing and assess how well they work amid real terrain and civilian activity. The reporting did not establish that every incursion was hostile, making detection and classification as important as response.
