Light Marine Air Defense Integrated System (LMADIS)
This United States Marine Corps portable jammer is making waves left and right. And for good reason. This thing took down a threat in the form of an Iranian drone earlier this year, launching into the sea. How? This bad boy jams the signal between drones and their operators, leaving them to carry on at whatever course they are on until it runs out of batteries or hits something. In this case, right into the sea!
