The objective of military fleet operation is to satisfy uncertain demands on time while providing vehicle maintenance. The ease of assembly and disassembly of modular vehicles enables them to achieve real-time fleet reconfiguration, which is proven as beneficial in promoting fleet adaptability and in saving ownership costs. Fleet modularity provides extra operational flexibility through on-field actions, in terms of vehicle assembly, disassembly, and reconfiguration (ADR). Modular vehicles are vehicles with interchangeable substantial components also known as modules. Such insight, we hope, might help make the assumptions of these models more behaviorally valid for counterterrorism risk analysis. We then suggest how some of these assumptions could be modified to describe terrorists' preferences more accurately, by drawing knowledge from the fields of behavioral decision research, politics, philosophy of choice, public choice, and conflict management in terrorism. However, are such assumptions reasonable from a behavioral perspective? In this article, we analyze the types of assumptions made across various counterterrorism analytical models that represent malicious agents' judgments and discuss their suitability from a descriptive point of view.

The standard assumptions in most of these models are that terrorists are fully rational, following all the normative desiderata required for rational choices, such as having a set of constant and ordered preferences, being able to perform a cost-benefit analysis of their alternatives, among many others. A recent trend in counterterrorism risk analysis is to model the terrorists' judgments, as these will guide their choices of such actions. A key objective for policymakers and analysts dealing with terrorist threats is trying to predict the actions that malicious agents may take.
