I try very hard not to and I do not mean to suggest anything to the contrary. It is simply my experience that people who believe themselves to be knowledgeable on the subject (or use it as some kind of talking point) like to reduce it down to industrial simplicity and inevitability.
I'm still learning stuff on the subject. People tend to want to reduce things to their basics, but sometimes large complex endeavors define such generalizations. Yamamoto aparently knew the tremendous industrial capacity of the United States and how long it would take for the "Sleeping Giant*" to awake. His prediction to the Japanese War Cabinet was he could "run wild for six months", but gave no guarantees after that for he knew America would be mobilized and pushing back at Japan's territorial expansion. In fact, exactly six months almost to the date after Pearl Harbor, the first carrier vs carrier battle unfolded in the Coral Sea as the United States Navy challenged the Japanese invasion of Port Moresby in New Guinea.
*The Sleeping Giant quote is used in two movies about Pearl Harbor, but may be a theatrical invention in the end.
Kursk is a great example. Visions of Enemy at the Gates; seem to dominate cultural understanding of the Eastern front. I think the idea that the Russians could have bested the Germans because of tactics and not by shear numbers alone would be unusual to many people.
If you look at the continued clashes between the Israelis and Arab nations in the Middle East, you'll see tactics and tenacity of individuals prevailing over technology quite often although there have technical surprises that got best of Israelis on more than one occasion (The Egyptians caught the Israelis totoally off guard in 1973 with tactics and some technology like Anti-tank missiles such as the Sagger and advanced SAMs like the SA-6, but crossing the canal was a true coup with water jets used to dissolve the huge sand berms). Of course, the Israelis turned the tables on the Egyptians with their own crossing and then cutting off the invading armies. Only thing common to all conflicts is the key individuals making decisions either on the battlefront or far in the rear that have short, mid and long term implications for success.
I don't mean to be typing here asking for answers and the abbridged version; I've merely been thinking aloud (for better for worse ).
Pretty good questions, don't apologize for them.
