Theme

 In the book, Fallen Angels, the main character Perry is waiting in the bushes with his squad for the Vietnam patrol to pass by the ambush that they have prepared for them. before they took off for the patrol they had a discussion on teamwork and how it will help them win the battle and the war and was going to use it in the ambush that they were about to get ready for.

The theme in the book Fallen Angles is that teamwork is key to win. One of the main actions in the book Fallen Angles was when they ambushed the Congs when the Congs were trying to ambush them. The USA soldiers had a plan and was very outnumbered so if they all just ran out at the Viet Congs they would of been shot down easy. 

My other reason is that in a war where you are fighting against another country on there own territory you need to computerate as well as possible to win the war because they have the upper hand. With the help of the NVA they got a better understanding of the terrain and how to use it. That is another example of teamwork.

The war wouldn't have been won without teamwork because the US was way outnumbered but just outplayed the Vietnamese. They couldn't of done that without teamwork.
