To establish a Department of State Domestic Protection Mission relating to unmanned aircraft system and unmanned aircraft.

HR 1386 authorizes the Secretary of State to counter drone threats to specific U.S. Department of State facilities and assets (like embassies and diplomatic compounds) by allowing actions such as detecting, disrupting, or seizing unmanned aircraft systems without prior consent. It requires coordination with the Federal Aviation Administration to ensure airspace safety and includes strict privacy safeguards for communications intercepted during these operations. The law applies directly to drone operators near covered State Department sites and mandates annual congressional briefings on its use, with authority expiring after seven years. The bill does not create general drone regulations but focuses solely on protecting State Department missions.
