The HMMWV has set the world standard for army tactical vehicles, since its introduction into the US Army in the 1980s. The Humvee marks another step in the evolution of small tactical vehicles, first started by the legendary Jeep of World War II. Modern armies have a need for a larger vehicle able to carry tactical radios and other equipment too large for a vehicle like the old Jeep. Due to its larger size, the Humvee has proven to be adaptable to a wide range of roles, including weapons carriers, missile launchers, command vehicles, and other specialized types. This book traces the development of the Humvee and its many variations, including the latest families of armored Humvees used in Iraq, in 2003-05. It will also briefly cover the proliferation of Hummer clones in other countries, as well as the civilian versions of the HMMWV.
