I think it's healthy for people to admit they're scared. I think it's normal. Emotional honestly is healthy. What is unhealthy is being controlled by that fear. When you're able to overcome fear to get the job done, that's courage.
I'm sure 90% of soldiers are scared before heading into a fire fight. But most do the job in spite of that fear. That's courage.
100% of soldiers are scared. I was scared but chose go act when fired at. The ones not scared you want the fuck out of there since they make bad decisions. Same when I was bouncing. The ones liking and therefore looking for fights were kicked to the curb fast.
The best ones dont like fighting but know how. Those are the ones to be frightened by.
