I love your spirit and admire it just as I had it back in days.
But trust me, things are so fixed that you can't change a bit. Not as a Brigade or Div Commander, let alone Platoon Commander as a Lt/Capt or Major.
The only thing they'll evaluate in your personality during ISSB is if you can be broken, reshaped. If they feel not, they'll put you out. PMA is where they break a person, reform him into their own system. Who works accordingly and doesn't step out.
I know how badly eager you're to fix things up on your level, but they'll pick you out like a fly.
