NBJ and NFD are two training fields used heavily by joint service military primary flight training based in NAS Pensacola and NAS Whiting field. On an almost daily basis; GA aircraft transiting the area enroute to PNS; JKA; CQF and 5R4 fly directly over these military fields below 1500' AGL and directly through the patterns with several active aircraft. Most GA pilots would never do this over a civilian field; but for some reason have no qualms about doing it over these fields; even though they are on the VFR charts. They are both under low Class E airspace; yet GA pilots are not using See and Avoid or they would not be flying through a pattern occupied by multiple aircraft. Maybe since they don't see an associated VHF CTAF to call for position reports or just plain ignorance; GA pilots seem to think these fields are inactive. In fact they are heavily used on a daily basis and several near mid-airs occur in any given week. Something as simple as adding a note on the chart with the pattern altitudes; a distance to avoid around these fields; or to contact PNS ATC for traffic reports on these fields may alleviate some of the problem. If not; something unfortunate will happen.
A military instructor pilot reported NPA and NDZ outlying training airports NBJ and NFD are subject to daily VFR civilian traffic over flights below 1;500 feet without CTAF traffic calls. Both airports are heavily utilized and traffic conflicts occur daily. Better VFR charting notices may help.
