As I recall USNG was not expected to field competent divisions with out 6 months of retraining. I think that was borne out by GW1991. Little or no new weapons would be added for months because it would take that long to retool factories for old weapons. I could see whole-sale upgrading of old equipment and most emphasis on munitions production provisions and fuel stocks. New weapons would require retraining and restocking parts & building up ammo stock piles.
Lots of ATGM [TOW/HOT/MILAN] deployed on all kinds of APC & ICV, while sales of Stinger missile should sky rocket. But the WARPAC can be expected to take similar steps.

The Warsaw Pact already had a war economy. Their military couldn't get much bigger. It was pretty much maxed out.
