How about an RC quad copter with CCTV and TH3 [thermite] grenade? Hover over the tank's engine deck and drop the grenade. The U.S. M14 TH3 grenade burns at 4,000 degrees Fahrenheit and would easily burn through the steel engine deck and into engine. The molten metal would set the diesel fuel and oil afire. The fire will either immobilize or destroy the tank when it reaches the ammunition stowage.

You don’t have to drop it, you just kamakazi the drone with its thermite package into the tank. Drones cost a lot less than tanks.
