About the logistics thing: I think I'm with Teuf here. That whole "experts study logistics" thing is true, sure; but it's very, very trite. Because logistics is, in one way, very easy: Manpower.
Take my time as a conscript: I spent two and a half months in basic (and watch & security) training. That made me barely able to fight as an infantryman in a squad sized formation. Very barely.
On the other hand, it took not even a month to get my MOS as a logistics guy for headquarters & service companies, the same MOS the lower-ranked NCOs in the materiel squad had. Other guys in the first company? Truck drivers, fuel, ammo, repair? All one month, maximum two. At the lower ranks, logistics are easy to do, and manpower needs are easy to fill.
Switching over to the guys from basic who went to the fighting companies: Tank driver, two months. Gunner? Not withing additional voluntary service time. Gepard gunner? Four months. And that is the minimal training time; no field exercises, nothing advanced. Others around here will known how long it takes to train a really competent infantryman.
Looking at that lower end of the food chain, re-growing the tail is easy. Re-growing the teeth is not. You can teach someone to put a bomb on a plane in a few hours, I guess, but you can't train him to fly it (more than once).
That is where the real division between logistics and fighting troops lies, methinks, and why it is important.
