1. While the team was marching, the sentry found the body of an American soldier on the hillside. The commander was about to send someone over to check the identity of the deceased, but Zach casually tried to dissuade him. The commander did not listen to the dissuasion, but the soldier who went to check was killed by a landmine attached to the corpse——

Zach: The dead man is just a corpse, no one cares who he is.

2. The team intercepted a group of fleeing civilians on the way. Sergeant Blount, nicknamed "Father Paul", had the following conversation with Zach while searching them——

Blunt: They all look the same to me.

Zach: Don’t you know how to tell the difference, Father Paul?

Blunt: No.

Zach: The South Koreans will want you to run with them, and the North Koreans will chase you.

3. Zach agreed to escort the North Korean officers to find the main force at the cost of a three-week vacation in Tokyo. Before leaving, he did not forget to joke with the sergeant nicknamed "Buddha Head".

Buddha Head: When I leave here, I will join the Air Force, and the bugs will not be able to bite me anymore.

Zach: Be smart. Nothing compares to infantry. You're flying a plane and what happens if you get hit? You haven't fallen to the ground yet. You will also suffer double physical pain. If you're on a boat and get hit you'll drown. In the tank, you'll be like an omelette in a pan. But as an infantryman, you only get bullets. Either dead or alive, but at least you're still on the ground. There is no better way to be smart than to be an infantryman.
