On his second combat tour, Nick Brokhausen served in Recon Team Habu, CCN. This unit was part of MACV-SOG (Military Assistance Command Vietnam Studies and Observations Group), or Studies and Observations Group as it was innocuously called. The small recon companies that were the center of its activities conducted some of the most dangerous missions of the war, infiltrating areas controlled by the North Vietnamese in Laos, Vietnam, and Cambodia. The companies never exceeded more than thirty Americans, yet they were the best source for the enemy's disposition and were key to the US military being able to take the war to the enemy. This was accomplished by utilizing both new and innovative technology, and tactics dating back to the French and Indian Wars.

This small unit racked up one of the most impressive records of awards for valor of any unit in the history of the United States Army. It came at a terrible price, however; the number of wounded and killed in action was incredibly high. Those missions today seem suicidal. In 1970 they seemed equally so, yet these men went out day after day with their indigenous allies - Montagnard tribesmen, Vietnamese, and Chinese Nungs - and faced the challenges with courage and resolve.

Whispers in the Tall Grass is the second volume of Nick's riveting memoir of his time with MACV-SOG.
