Although the role of the military advisor to senior foreign officials is honored in political history, it became almost a forgotten art when it was needed in Afghanistan and Iraq. American military services are now fully engaged in nation-building in the Iraqi and Afghan conflict zones, and the advisory responsibility seems certain to be needed elsewhere. Advisors have become an invaluable part of the nation-building process, and whether they are assigned to counsel and work with governors, generals, or Cabinet Ministers, their role has an impact on America's overall political and military strategy. This guidebook draws on the experiences of diplomats and military officers who have served in such roles, and whose work with senior foreign officials was carried out in conflict zones at critical times. Although examples are drawn from life in the Islamic world, the precepts have widespread application, and the examples will be an important part of any future advisor's preparation.
