That's good advice. I have been in a lot of shitty situations so I know very well how it goes and how bad it gets. I also had a privilege to talk to a lot of combat veterans from the Croatian 90's fall of Yugoslavia war , and other than listening to war stories I would often ask them about mental aspect of war. I was told that the most important thing once you decide to fight is to come to terms with your own death, and accept that there is a great chance you will die fighting for the cause. You must be ready to die. About killing, you can be ready as much as you want, but most people react to it differently. First time some will break down and be out of commission for days, while others won't be affected much or will deal with it internally. I guess if you really hate the enemy there shouldn't be an issue. They all said that second kill would be business as usual. Few of them who had to do it, told me that the worst thing they ever had to do in the war was to go to the home of their fallen comrade and tell his family that he is dead, even worse if there is no body to bring back. This is why they would always do everything they can to extract the bodies, even from the minefields. Honestly this aspect of the war never occurred to me, and I can only imagine how horrible it would feel. Also I was told always to carry an spare bullet in the shirt pocket, if you ever run out of ammo in a wild and unhinged war like that, it's better to kill yourself than fall in enemy hands. Serbs used to execute prisoners by chainsaws, pulling them apart with 2 cars or roasting them alive on a spit over fire. Now imagine what niggers and jews would do.
