Military taxonomy encompasses the domains of weapons, equipment, organizations, strategies, and tactics.^[1] The use of taxonomies in the military extends beyond its value as an indexing tool or record-keeping template.^[2]

Military theorist Carl von Clausewitz stressed the significance of grasping the fundamentals of any situation in the "blink of an eye" (coup d'œil). In a military context, the astute tactician can immediately grasp a range of implications and can begin to anticipate plausible and appropriate courses of action.^[4] Clausewitz' conceptual "blink" represents a tentative ontology which organizes a set of concepts within a domain.

A conventional military taxonomy might be an hierarchical set of classifications for a given set of objects; and the progress of reasoning is developed from the general to the more specific. In such taxonomic schema, a conflative term is always a polyseme.^[5]

In contrast, a less conventional approach might employ an open-ended contextual military taxonomy—a taxonomy holding only with respect to a specific context; and the progress of reasoning is developed form the specific to the more general.^[6]

A taxonomy of terms to describe various types of military operations is fundamentally affected by the way all elements are defined and addressed—not unlike framing.

In terms of a specific military operation, a taxonomic approach based on differentiation and categorization of the entities participating would produce results which were quite different from an approach based on functional objective of an operation (such as peacekeeping, disaster relief, or counter-terrorism). An incidental advantage which flows from give-and-take in refining taxonomic terms more accurately and efficiently becomes more than a worthwhile objective in terms of anticipated outcomes or results. In today's nontraditional operations, the discussion about fundamentals also generates greater precision in how the defense and security community understands and discusses integrated operations.^[7]

A number of military strategies can be parsed using a taxonomy model. The comparative theoretical framework might posit a range of criteria, e.g., the character of envisaged political goals, the type of military strategy preferred, and the scope of forces engaged; and this template suggests discrete modes of force. The taxonomy-model analysis suggests a useful depiction of the spectrum of the use of military force in a political context.^[12]

Taxonomies offer useful, but incomplete means of structuring information.^[13]

Taxonomies are a necessary but not sufficient condition for adequate evaluation of a given data set. While the taxonomic categorizations and sub-categorizations do enhance understanding, it may be significant that the lack of detail in describing objects or elements creates room for ambiguity.^[13]
