New Enemies begins in September 1950, just three months after the World War II Series finale, Nazi Plunder, ended. Tom Dunn, currently working as a police detective in Kansas City, Missouri, feels a call of duty and volunteers to rejoin the new Rangers.

Traveling to Ft. Benning, Georgia, Lieutenant Dunn joins a Ranger company as a platoon leader as they go through the grueling Ranger Training Center's eight-week training program. Not everything goes smoothly, but after the company graduates, they are finally on the way to Japan, and their final destination, South Korea. They arrive in late January 1951, and are going to be in the throes of the Korean Peninsula's bitter, brutal winter.

Assigned to the Eighth Army's 24th Infantry Division headquarters about fifty miles southeast of Seoul, South Korea, the new Ranger company is tasked with three missions, taken from history. They are thrust immediately into action. Starting with a long incursion combat patrol into enemy territory, they encounter the enemy. Can Dunn solve the challenging tactical problems that lay in front of him?

Another mission takes them in to the Saje-ri Twin Tunnels, two mile-long railroad tunnels west of Wonju, South Korea. They are to clear the tunnels with the help of a platoon of five Patton tanks, but naturally, things don't go according to plan. Can they eliminate the Chinese Communist Forces surrounding them and return to the American front line safely?

In New Enemies, Munsterman introduces us to the men who fought in what was for a time called The Forgotten War. Once again he masterfully blends historical fact and fiction to create a compelling story of Tom Dunn and the U.S. Army Rangers. Their courage and dedication to each other exemplify the Rangers. In his usual page-turning action style, Munsterman carries us along in a gripping story illustrating the importance of why we were in South Korea: to save the people of an overwhelmed country from the hell of communist control.
