Seems that the mobilization hassles are more pronounced with equipment than with personnel, when we're staging to do something. Getting a couple thousand troops to anywhere in the world isn't a serious challenge anymore; getting the equipment and materiel to make those troops functional and effective is much more so.
I like the idea of pre-positioned and stocked "depots", heavy on equipment and materiel, light on personnel; security and minimal support personnel only.
Not so much for the typical "not have all your eggs in one basket" line of thought you hear often on these boards regarding supplies and caches - that's to separate resources in case one site is compromised, damaged, whataver. This is just to reduce the distance equipment needs to be moved when needed, and the time & resources needed to do so.
Smaller facilities, in more locations, makes for more options and flexibility. That's how we (actually, the Romans, iirc) came up with the "regiment", "company" and "squad" ideas. Until then, an army was just one huge entity. Sub-dividing makes for flexibility, both with personnel and materiel.
