> ATGMs like Javelin, mines, guided mortars, etc and all but the heaviest drones are defensive and supporting weapons. Naturally they're defensive. Tanks are offensive weapons; breakthrough armor, conceived to break WW1 lines. So weapons to defend against tanks have proliferated. The question is has this proliferation made them obsolete? Can you still effect breakthroughs when a guy with a tube can kill armor from 5+ km away? And if his man portable tank killer can't do the job he can text a missile from 50+ km with a anti-tank precision warhead so big there is no mobile armor system known to man that can withstand it. You can't have a Battle of Kursk when one M270 could theoretically kill a dozen tanks every five to ten minutes.
