They were public schools, but 3 were located within the military family housing area.
Most of the students lived in the “North” housing there (including my kids ... pre-homeschooling), a few came from other areas just outside of the base and from smaller base housing across the dividing highway, where the actual Air Force Base Buildings & other services (commissary, BX, hospital) were located.
There may have been some kids bused in from other housing areas, but most of those would have gone to the C.B. Lamb school. I don’t think there were many kids at Ft. Dix, that was mainly Army training and most likely had their own school system there (it’s a huge complex of bases)
If they are public schools, then the Lt. Col. has no business injecting himself into a political debate. Neither does the base in any official capacity.
