It makes sense. A military is only as good as its logistics, and the US’ forward bases are the tips of very long spears, dependant on a lot of logistics. So you need to have the means to have a continuous pipeline of supplies to each outpost. In peacetime, you keep that open by supplying the troops with burgers, tacos, XBox games or whatever; if the shit does hit the fan, all that capacity can be diverted from tortillas and patties to ammunition, drones, amphibious landing craft or whatever, at short notice.
