It's a good phrase I think. And there's been several respectable militaries who adopted it as a core principal, notably the japanese and germans. It was expected that junior officers would disobey orders if they saw a massive opportunity their superiors weren't responding to. Guderian did it during WW1 when he pushed was ordered to halt in the middle of an assault but instead he kept his troops pushing and captured an entire enemy unit before they could consolidate at a new position. The japanese invasion of manchuquo was also undertaken on the initiative of (relatively) junior officers.
