Retired Brazilian Army Major General Alvaro de Souza Pinheiro, in his monograph highlights the importance of knowing our partners. General Pinheiro begins by presenting a Brazilian point of view of the post-9/11 world. He then presents a history and over view of Brazilian SOF units from the Army, Navy, Marine Corps, and Air Force. Modern day Brazilian Army SOF pioneers attended U.S. Army schools and founded Brazil's Special Operations Course in 1958, which later expanded to include Commando Actions, Special Forces, and Jungle Operations qualifications courses. In 2002 the Brazilian Special Operations Brigade was created by presidential decree. As U.S. Special Operations Command looks to thicken the global SOF network, General Pinhiero's monograph is a must read for the American SOF operator in order to better know our partners.
