The Avenger Air Defense Missile System

Avenger consists of eight stinger missiles and an M350 caliber machine gun designed to protect U.S. Army forces from low level air attack. Avenger is typically mounted on a Humvee, but the Washington system appears to be mounted on a pedestal on top of buildings around the White House. Machu Picchu and the Parthenon are landmarks that you can't fly over unless you're at least 5,000 feet above it. US Airlines and other foreign carriers cannot fly over Russia because of the Russian-Ukraine war.
