The book sets forth the role and place of reconnaissance in modern combat; its division into constituent parts; the demands made of it; the goal, missions, and objectives of reconnaissance; and the components of reconnaissance, the men and equipment, and the methods of reconnaissance. The fundamentals of organizing and conducting reconnaissance in the main types of combat are explained. The problems of assembling and processing intelligence information are considered. Reconnaissance is a highly important form of support. It is required to furnish the command element and staff at all levels with the information about the enemy, the terrain, and the area of impending actions that is needed for successfully preparing and conducting combat actions.
