Considering the issues existed in the research results of current combat intention identification and predictionsuch as too few typestoo coarse granularityand lack of targets and objective of attack in the selection of combat intentionsas well as the demand for intention recognition in the future equipment development and mosaic war environmentthis paper analyzes the formation process of combat intention and the relationship between combat intention and the behaviorand introduces the explicit and implicit attributes of combat intention.Combined with mosaic operational requirements and the reality of multi-domain joint operationsthe combat intention is decomposed by typesprocessesstates and rolesand a three-level granularity model of combat intention is establishedwhich realizes the multi-levelmulti-attribute and multi-granularity detailed modeling of combat intentionand provides reference for the identification and prediction of combat intention.
