The virtue of defining and measuring the commander's performance solely on their "knowledge in their heads" has become an important part of reconstructing battlefield sensemaking process. It is assumed that the expert commander constructs diverse and asynchronous sensemaking models when confronted with asymmetric situations-evolving and changing dynamics of the battlefield information. This personal construct systems are not static-they are confirmed when patterns of old information match the current situational goal, or challenged every moment the commander realizes that everything "held in the head" is no longer relevance-and thus, a new construct system has to be developed quickly to adapt to the new situation. Some of these constructs represent the commander's atypical belief and core values, which can be expressed intuitively by using heuristics, or explanatively by testing wide-ranging hypotheses using mental models. We extend Kelly's construct theory to model the commander's sensemaking process based on his/her field experience. Information from expert interviews with the field commanders from recent conflicts in Iraq and Afaghistan are used to develop the principles of individual sensemaking constructs based on evolving battle situations.
