Nowadays with GPS I imagine much better accuracy.
Of course with nuke rounds, (which we never did fire during the Cold War, thankfully), impacting in one grid square was close enough.
The Soviets didn't think so. Their artillery planning included protocols for an entire corps to deliver their airtillery payload time-on-target into a single grid square, everything from company-level mortars to 200mm+ field arty' plus barrage rockets. No idea if they included their 152mm- nuclear rounds in that deliver, but I'd not be surprised if one or two was in the mix, just to be sure,
No wonder Ivan calls his artillery *God of Battle*....
А что такое современная война - интересный вопрос, чего она требует? Она требует массовой артиллерии. В современной войне артиллерия это бог... артиллерия решает судьбу войны, массовая артиллерия.
[And what is the modern war, it's an interesting question, what it requires? It requires massive artillery. In modern warfare, artillery is a god... Artillery, massive artillery decides the fate of the war.] --Josef Stalin (1940)
