Re: no B course AAR.
I've had a lot of B course students in both the F-100 and A-7, and I've never heard of a student being released from the course before satisfactorily completing all the syllabus requirements including night AAR and night ground attack in sequence as well as any task specified as requiring a dual ride. We had one that had to do 4 night formation landings in the F-100F (first 3 graded unsat with IP intervention) and had to return to finish the course after XMAS.
Actually same was true of the C and I courses, nobody left before completion of all elements.
I wonder if this is standard now, COVID related or what? AETC passing the buck to the ops units. Why did he have to return to SC before completing the syllabus? Operational unit instructors tend to have a bit different mindset regarding training than dedicated formal training unit B course instructors who see the initially 'less skilled' side of fighter aviation regularly.
