I think all the Bdes rotate their Units through IRU. The IRU would have a Coy strength Sub-Unit on 24 hrs notice to move, with the rest (Bn strength) on 24 to 48 hr NTM. These, however, are not really set up for International Deployments, but Internal Deployments within the Bde AOR. It would be good to set up a more enhanced DART, and actually permanently post a larger contingent to it. As it sits now, most of the DART is pulled out of Pet, with only a few Sup Techs and others, permanently maintaining what little stores and equipment they have in Trenton.
If all these ideas come to pass, then Trenton would not be large enough to house any or all of them. The Government would have to expend Billions of Dollars on the purchase of land, construction of more runways, construction of hangars, construction of barracks and PMQs, infrastructure, roads, railheads, fuel dumps, etc. (This is thinking of all the promises to put an Airborne Unit, C17s, Hercs, DART, JTFNBC, and whatever else in Trenton, besides the existing Air Force. An awful lot of eggs in one basket.)
