Supply/Logistics Question

[kalos72]

So I have seen some numbers of 600000 M-16 in US Military stores...

From the best I can tell, we added maybe 60-70k in new "training" divisions during the war...leaving 500kish M-16's in US inventories.

Does the US store this level of weaponry? Where?

Do they have the same level of supplies for things like kit/clothes/battle gear?

How do people feel about the "us_army_build-up_and_mobilization" document? Seems like there is ALOT of possibilities for creating new light units if you can get the training organized post TDM. Assuming the supplies are there...some where.
