Anyway, here's something from the May 1943 issue, from an article detailing photographic reconnaisance.
T/Os of each Air Force headquarters call for a photographic group commonly consisting of one photographic heavy and three photographic light squadrons. A photographic squadron has two flights of four planes each and one of five planes. Heavy squadrons, for long range flights in reconnaissance and mapping, use the B-17 and B-24 equipped as for bombing missions except that they have cameras and extra fuel instead of bombs. Medium squadrons of B-25, B-34, A-29, F-2 and F-3 planes are seldom used. Light squadrons use the F-5A, substantially a P-38 without armament.
