What is mentioned in this book, it is war. A part of the war was specially trained and trained under US policy, commonly called the Special Forces. During the Vietnam War how was that special unit trained? What did they do in the Vietnam battlefield? How did their successes and failures take place in the battlefield of South Vietnam? The content of the book contains many articles by many authors, most of whom are members of the Special Forces. Their mission is to rescue the prisoners of war, to investigate and cut off the surface communications, to organize marches into the enemy's area to control, to get intelligence on the war ... And what happened to them, to their teammates in the operations?. The stories are with different colors such as: Intrusion into the VC’s rear area and encountering the enemy; Flights that looking for a place where Special Forces will be landed; Flights whose purpose was rescuing the Special Forces under the enemy fire; Enemy’s attacks into Special Forces camps (Lang Vei, [Lang Vay - that near Khe Sanh?] Kham Duc [Kham Đuc?] ...); Special Forces success & failure ... All that are conveyed very detailly by the author, sticking to the content of the problem. War is over, what happens is the past, and we can not change the present of history. It is a hope the book helps us and future generations to understand more about war from the perspective of the soldier on the other side and help us read in the research and investigation of a certain piece when writing about the history of Vietnam War.
