It was some time extreme chaotic, thanks to NSDAP bureaucracy
some examples
My german granddad had to move to North Africa, to fight on front under Rommel,
Thank in last minute change in Wehrmacht bureaucracy, he end up in Leningrad.
with Tropical equipment in russian winter !
He survived this only to end up in 6 Army under Paulus in Stalingrad.
here Göring promise Hitler the Luftwaffe could supply them, in realty 6 army was a starving.
Also had the Luftwaffe and Tank divisions of SS and Wehrmacht,
the Problem not to get there petrol/Ammo on time or hardly enough to run there equipment...
the V2 program had also similar insane Logistics system.
the parts were made allover the Third reich and had to be move by Train hundreds of kilometer to Mittelwerk.
what make it a easy prey for US Bombers
Sorry, but i do not think, that your examples proving that German logistics was a joke - well, most of the problems you mention have nothing or barely do with logistics at all (at least in the classical sense).
In the case of your grandad's, i think, it have to be a reason for that quick allocation: from the special knowledge to the urgent need of warm bodies on that sector (in ww1, after the italian dow, many lower level AH officer tought that the "brass" contains only dorks, since they got rerouted to italy sometimes from galicia while the upper echelon congratulated themselves, that they could get the troops for the front - matter of perspective).
Regarding his uniform and equipment, no suprise, that in a "last minute travel" he did not get new - but in his destination, i think, he got it issued, right?
The Stalingrad air bridge, well, up to that point, no one even tried to supply troops trough air besides the germans. And since they succeded it Demyansk (and that was anything, but logistical joke!), they tried it again - but in this case, i blame Göring, and his bragging habits.
The armoured divisions of the WH, WSS, LW is not logistical issue, but system failures: everyone built their little empires.
And the interesting thing: despite the "common knowledge" ammo/petrol/food shortages due logistical failures by the germans were - lets say not that common.
In case of the V2 issue, its not a logistic problem - and its not even bad, either, if you concentrate your production efforts in one location, it makes a delicious target (Peenemünde, khm). (And you will always depend on transportation, no matter how you concentrate your production).
The allied attack on german transportation (train network mostly) was logical - indirect - way to hamper german warmaking capabilities.
Again: no matter what you do, you always have to transport! The question is, could you manage to do it? Could you overcome the problems?
