What is Military Intelligence? Military intelligence is the product of gathering information about foreign military dispositions, equipment and strategic plans, analyzing the contents of that information, and disseminating the findings to decisionmakers. It appears in three basic forms — tactical, operational, and strategic. Tactical intelligence concerns information about the enemy that is designed to help decide which tactics, units, and weapons will most likely contribute to victory in an assigned area. It is a short-term, narrow-use tool that, when properly applied, can be a significant force multiplier. Operational intelligence assumes a broader approach. Its purpose is to conduct military campaigns that accomplish strategic objectives within specific areas of operation. Finally, strategic intelligence involves a focus on more overarching, but static factors such as geography and infrastructure; or long-term trends, such as the application of new tactics or the development of new resources. Strategic intelligence is an important tool in the effort to anticipate and counter threats throughout the world. The intelligence process services the need for both tactical and strategic intelligence. The first step, information gathering, consists of collecting data and making it available for analysis. A common method of information gathering is the use of unclassified “open sources,” such as foreign websites, television, newspapers, radio, or openly published government studies. Often, this open source intelligence (OSINT) provides such basic information as population statistics, military maneuvers, and political, social, and cultural trends. Open sources sometimes do not supply enough information, and other techniques are often necessary. Analysis of aerial imagery is one commonly employed method. A great deal of information can be gleaned from photo interpretation of detailed high-altitude pictures — so-called IMINT, or imagery intelligence — of a nation’s infrastructure, military bases, and even troop movements. Human intelligence (HUMINT), signals intelligence (SIGINT), and measurement and signature intelligence (MASINT) can also provide military advantage over foreign enemies. All of these sources provide vital intelligence that, when properly analyzed, can provide a significant benefit to warfighters and policymakers. A History
