What is it that makes a great soldier?

We all knows that this question came from Hell’s Highway but really what is the best choice?

I’d asked in several different website and (sortof) spike an argument there.

Which option do your guys thinks that really makes a great soldier? You can only choose one.

Having the back of the comrade beside you

His heart

Ready to give his life for the brother next to him, would be my response.

Now if i had to answer between his brain/heart, i’d say a bit of both, depends on the situation, things aren’t that binary in life.

Having an exta portion luck is the key imo.
