“Just as discipline and freedom are opposing forces that must be balanced, leader…” — Jocko Willink

Your success, or lack of success, is your responsibility. Even when you have a chain of command that you don't like as well, its your responsibility to work with the up chain of command.

Perseverance is also key to success in any endeavor, but without perseverance in combat, there can be no victory.

Since the team understands that the leader is de facto in charge, in that respect, a leader has nothing to prove. But in another respect, a leader has everything to prove: Every member of the team must develop the trust and confidence that their leader will exercise good judgment, remain calm, and make the right decisions when it matters most.

If it's stress of things that we cannot control, what you have to do is you mitigate that stress as much as possible. You've planned, you've trained, you've done everything you can in your power to mitigate the stress that's facing you. And then after that, there's nothing you can do. So, you have to let that one go.
