Yes, spreading out the troops for some sort of impending attack on the installations. It follows the exact same doctrine that the soviet army uses for it's mobile strategic rocket forces. Rather then place critical assets in hardened, fixed locations, you keep them VERY mobile and during time of war, you flush or scramble them into different locations in the countryside to avoid being taken out all at once. Once the bombs have fallen, you can re muster them centrally again if needed. Question is, did they take their basic gear, weapons, comms etc home with them? If so, there is your answer I think.
