<p>Osprey's study of airmobile tactics used in the Vietnam War (1955-1975).</p> <p> With its first major use in battle during the Vietnam War, the helicopter ushered in a radically different way of fighting, despite its proven vulnerability to ground fire. Either delivering troops into hostile territory and removing them after the fighting ended, or armed with guns, grenade launchers, and rockets to provide rapid and wide-ranging air to ground support fire, the helicopter - available for the first time in sufficient numbers and capable of a wide range of missions - played a central role in the war.</p> <p> From the beginning, with obsolete Korean War helicopters carrying ARVN troops into battle, to Huey gunships evacuating the wounded at la Drang in 1965, and transport helicopters evacuating Americans from Saigon rooftops in 1975; this was the first real helicopter war. By the middle of the war, the helicopter, in particular the Huey model had become as important to the army as the tank, the armored personnel carrier, and the jeep.</p> <p> Presenting a concise history of the first ever major use of helicopters in battle, Gordon L. Rottman, a former Green Beret in Vietnam, describes in detail the development of the critical airmobile tactics that ultimately changed the way America fights its battles.</p>

The first edition of "Gaia's Garden" sparked the imagination of America's home gardeners, introducing perm culture's central message: Working with Nature, not against her, results in more beautiful, abundant, and forgiving gardens. This extensively revised and expanded second edition broadens the reach and depth of the perm culture approach for urban and suburban growers. Many people mistakenly think that ecological gardening, which involves growing a wide range of edible and other useful plants, can take place only on a large, multiacre scale. As Hemenway demonstrates, it's fun and easy to create a "backyard ecosystem" by assembling communities of plants that can work cooperatively and perform a variety of functions, including: Building and maintaining soil fertility and structure; catching and conserving water in the landscape; providing habitat for beneficial insects, birds, and animals; growing an edible "forest" that yields seasonal fruits, nuts, and other foods. This revised and updated edition also features a new chapter on urban perm culture, designed especially for people in cities and suburbs who have very limited growing space. Whatever size yard or garden you have to work with, you can apply basic perm culture principles to make it more diverse, more natural, more productive, and more beautiful. Best of all, once it's established, an ecological garden will reduce or eliminate most of the backbreaking work that's needed to maintain the typical lawn and garden.
