What is defined as a tactical conflict between opposing forces?

The term that best defines a tactical conflict between opposing forces is "battle." A battle typically represents a significant confrontation in warfare where organized forces engage in combat with the intent of achieving strategic objectives. This classification entails larger-scale operations than other types of conflict, allowing for the deployment of various military units and tactics.

Engagement can refer to a smaller or less formal interaction in warfare and does not necessarily imply the scale or intended strategic outcome associated with a battle. Skirmish describes a minor or preliminary conflict, usually of short duration, and often occurs on the periphery of larger battle engagements. An operation refers to a broader concept that encompasses strategic, tactical, or logistical activities carried out during military campaigns, rather than focusing solely on the clash itself.

In summary, a battle encapsulates the essence of a tactical conflict, characterized by its scale and significance in military terms, distinguishing it from the other terms listed.
