According to Global Research (www,globalresearchca) there are 800 military facilities designated as "bases" in the world and more 200+ major military "installations" (such as Barking Sands, Kauai).  In addition, there are innumerable military "training areas" (like Pohakuloa and Kahuku) and bombing sites.  The U.S. military footprint is much larger than the number of bases.
