This was probably said somewhere in this thread up toward the March/April 2022 time frame when the Russians had to pull back from their over-extended lines. Sun Tzu has some quote about Strategy without Tactics are the slowest route to victory. I've heard it in other context as "Strategy without Tactics are bloody minded." If your only plan is to get through the wall and you don't learn how to climb it you will break your nose trying to get through the wall. Basically, you are drawing arrows on the map without regard to how things occur. Tactics without Strategy on the other hand are futile. E.g., Its great you know how to engage the North Vietnamese with your helicopter-based forces backed with all sorts of airpower and firebases with accurate artillery fires, but is just killing NVA forces really a way to counter North Vietnamese war aims?
