Must have been a supply officer. Attacking the supply infrastructure of the enemy is a tactic. Defending your own supply chain is a tactic. Having said that, I agree with everything else you mentioned.
In order for tactics to be successful, there must be sufficient logistics to support the effort. Too many military leaders failed not because of poor tactics, but because their logistics capabilities could not support them.
Maxums are not necessarily crutches, but lessons learned that usually were bought and paid for with blood. As officers, we are always number three in the priority behind the mission and our men.
Oh, by the way, the distinguished military leader who stated that "an Army travels on its stomach" also failed to follow his maxum and was defeated by logistics in Mother Russia...Napoleon Bonapart!
