Holdover from the military. I can see you're framing it as "beneath", which would be very inappropriate, but it references "under your charge". Thanks for pointing out that it could be misconstrued.
I am sorry to hear you have not enjoyed your time leading a large group. It certainly has its challenges, but I assure you it can be quite fun and rewarding.
This is getting a bit too deep now. I didn't say that I didn't enjoy it. I like challenges, my initial notion was just to express that words like 'fun' are far away from what leadership is. Btw, you didn't answer the question if you led 100+ people for a longer time. Besides and no offense, military, authoritative leadership styles might not be the right approach in tech environments (like those where engineers work).
With regards to the military, good leadership works in any organization. I do not speak to my engineers the way I would speak to a platoon, but I lead them the same.
