It is infantry training, but there is a difference between providing infantry training as an experience, and training cadets to be infantrymen.
I don’t think that anybody running these courses will be expecting or trying to turn 14-year-old cadet Bloggs into Rambo. Instead, they will provide an experience which is representative (not necessarily wholly accurate) or being an infantrymen or in the RAF Regiment.
In the same way, we don’t train cadets to be pilots - there is no provision in the Corps (as far as I know) to allow cadets to attain a PPL. We can help them on their way, and provide them with an experience of what it is like, by providing air experience flying.
I don’t have a problem with cadets experiencing fieldcraft training with rifles any more than i have a problem with cadets experiencing flying.
In fact, I think cadets will really benefit from the teamwork aspect and some will fall over themselves to do it.
Some people though, allow personal bias on what they think cadets should and shouldn’t do and providing it’s in the spirit of the Corps - let’s have it.
