tbf ATGMs only make tanks infeasible if you have a massive supply of them continuously distributed to infantry units (and the latest fancy ones that aim for non ERA weakspots and have CCM against APS), which is what most if not all militaries struggle with.
Plus tanks get a huge buff in their effectivness when properly paired with IFVs and infantry, which can significantly diminish and counter ATGMs (and drones).
A big gun and survivability will always have a place on the battlefield. Until there is something else that can do what tanks can better, they will still be here
Yeah, APS can be a gun firing system or just a bunch of small fpv drones. The only real limit is safety restrictions, because a drone that is targeted to kill anything moving at it is going to have a good chance of hitting birds and people. That's something you could use in Ukraine if you have no civilians and your group is moving only in vehicles.
Automated target acquisition in that regard is prohibitively costly and therefore unlikely to be an option in that totally hypothetical anti-cop/acab situation, to be fair.
Whereas, consumer-tier FPV drones are not only super affordable, but they're only getting cheaper to produce (see: FDM printing) and in starling^1 quantities, too. (Hell, I got into the printing hobby initially to offset the cost of learning how to pilot a few myself years ago [ie. lots of crashes. lots.], and the tech has grown immensely since then.)
Just spitballin' here, ofc. 😅
edit: I'm leaving that misspelling ^1 as it seems both poetic & fitting, given the causational global proliferation of said bird by a hapless Shakespeare fan who only wanted to recreate the bard's local habitat to inspire himself by. I'd like to think that ol 'Bill himself'd take on wannabe-oppressors & sub-basement bigot babies all cosplaying as paramilitary heroes ("tacticool"), ya know?
