Someone part of the executive branch of the government would most likely belong to the diplomatic or legal class rather than a fighting class. Their role primarily focuses on policy-making, governance, and implementation of laws rather than engaging in physical combat. However, if we were to metaphorically assign a fighting class to someone in the executive branch, it could be argued that they would align more closely with the support class. This class typically provides strategic guidance, advisory services, and support to the frontline fighters or policymakers.
