I think the problems would be being in condition with your mindset and all, to be of service. To be able to focus well enough to take out the enemy, which is the objective. They would probably rather you not go in there with the desire to take out yourself. I was thinking along this line yesterday though. As miserable as I am I cannot bear the thought of suicide. But I can see myself doing something like Clint Eastwood did in that move "the Gran Torino", where he approached gang leaders unarmed to sacrifice himself in order to save the boy next door who was being hounded by the gang. Of course his character in the movie knew he was going to die a slow, painful death of lung cancer so he decided he would go out his way.
