Speaking of precision...

The APKWS is a 2.75-inch rocket with semi-active laser guidance for precision strikes in built up areas. It has been used by helicopters.
No BB needed either.
But who is winning the war if a $50,000.00 missile is fired from a 150 million dollar jet at a 500.00 dollar pickup truck carrying a machine gun? If the enemy doesn’t care about loss of (his soldier’s ) lives, who is really winning at that exchange rate?
A 20,000 ton heavy cruiser with nine 8 inch guns, armor and missile batteries, Sam and ciws could be built for a fraction of a carrier or battleship. You get heavy guns, tlam, and reasonable armored protect. Think a souped up Baltimore class or New Port News type ship.
