That's pretty much how long it would take the Soviet 2nd Echelon too arrive and move into the attack, give or take.
A piece of that Soviet 2nd echelon, is part of that Motor Rifle Division in places good Marxists don't believe exist.
NATO maybe on the short end of the numbers, but they've managed to cut into the Warsaw Pact enough to where that 2nd Echelon isn't as big and have to fight their way to the attack.
To break the stalemates, you have to get to them, and right now the Soviet commanders on the ground realize this. A smart pullback will give the Soviet the counterpunch you seek, but like anything in war, there is always a trade-off. The trade-off here is you've given you adversaries time to dig in build up and set up.
"better yet, attack in much quieter areas of the front."
But that's the rub. In the quiet areas are a bunch of yapping toy terriers. They hit they run, they leave and then they bring in some A-10 Thunderbolts and Harriers to pick off the wounded straglers.
The NATO teams are breaking the battlefield down into a lot of guerilla wars. Hit 'em where you are and where you ain't.
"That would likely delay things, only by two days at most"
In this type of war, hell any war, time is precious, be it seconds, minutes, or hours. A delay in hours of free troops and new equipment getting into the theatre is the difference between Soviet tanks pinching Stuttgart to the North, and gaining a major foothold and the Soviet marching into an empty city with enough wrecked T-72s and T-80s behind them to keep Fred Sanford in business for a century. They won the objective, but the price was so high that they lost an initiative.
For NATO planner at Heidelberg or Brussels, A two-day delay in Soviet reinforcement is Diana Rigg circa 1965. It's beautiful
"Getting the B-52 into the routes in Poland means running in large, unmanueverable bombers through some of the thickest portions of Warsaw Pact air defences (both ground and air). WP SAMs are going to be even more of a threat then the missiles were in either Vietnam or the Gulf War (both because the missiles themselves are better and the personnel manning them are better) and escorts are a dubious prospect.
A very fair contention, and a very real sticking point. Yeah, BUFFs are truly Big Ugly Flying Fellows...But in some skills hands, that unmanueverable bomber becomes something you can stick on a tree top and bring it through, and when you look at the guys who have to penetrate and stick a nuclear bomb on a first-down's worth of real estate, you are talking the best of the best.
SAMs? Yeah, they are going to be thick, but again...This is where having just a few ticked off people on the other side playing on your side can pay a dividend. You have a strike to carry out? You got a few ticked off East Germany students listening to a little Nina Hagen with an attitude with the right tools...BANG! No more SAM site. No more control bunker. True, it's hit or miss, but we're fighting for our NATO-Common Market bee-hinds here. I'll take an advantage anywhere I can get it.
Again, not saying it is easy. NATO is at the razor of the margins. What the NATO armies have managed to do is damn near superhuman and probably a better case scenario that an actual war under these conditions may have been, but war, like politics, never goes the way a textbook says in most cases.
