The Three Levels of Warfare

In contemporary military science, there are three commonly recognized “levels” of warfare and troop deployment: Tactical, Operational and Strategic. Here we will attempt to briefly outline these three levels, as some of the tactics described on this site have different meanings depending on the level they are deployed at.

The tactical level is the one in which maneuvers, engagements and battles are conducted on the battlefield. Here is where individual troops and small units up through to the divisional level engage enemy forces. It is a short-term dimension of warfare ranging from several hours through several weeks.

The next level up is the operational level, which is where, as the name suggests, operations and campaigns (which consist of multiple tactical engagements) are planned and conducted. This is where whole armies engaged in a theater of operations is managed.

Finally, at the top is the strategic level. Here is where military operations are considered in the wider context of geopolitics and long-term state policy.

The concept of “three levels” is not a universal science, but rather a way of looking at things. The idea began development in the early 19th century with Prussian general Carl von Clausewitz, who identified only two levels - tactical and strategic. Red Army officer Alexander Svechin proposed the operational level to cover the middle ground between strategic & tactical, an idea which would be expanded upon by the Soviets and ultimately adopted by the US military in the 1980's.

There are several other models built upon the Clausewitz-Svechin model. Some propose five or six levels, further breaking things down. Others propose a parallel “institutional” level, which is where warfighting capabilities (science, technology, education, etc) are developed. See diagram for more details.
