watso was reading that the houtis used low tech drones to confuse saudi defense systems - then would pop a ballistic missile over the border to hit some saudi infrastructure.
anyway, it seems that the houtis used drones to hit these oil installations . one thing for sure is that low tech underwater drones would make the australian submarines a target. the good news is that australia is having trouble finding the personnel to crew ships etc - so maybe the submarines will stay in port and be relatively safe
