You really are out of touch.
We run drill courses and they are always over subscribed. 100% positive feedback from the most recent Cadet Drill Course and many vocal supporters asking what other drill camps/courses they can do.
Whether you “get it” or not there are plenty of cadets who enjoy drill and ceremonial. These are the cadets who watch the QSC displays and think “I’d love to have a go at that!”. There are also plenty of staff who want to get more involved.
We have around 8 active DIs here and we all have a broader role, being involved in various other areas such as Skill at Arms, Comms, First Aid, AT..
Do stop grumbling and just deal with it - your idea of what the Corps “should be” is not the same as anyone else’s (and probably hasn’t been for the last 50 years).
