The paper describes the results of an experiment based on the use of constructive simulation in the MASA SWORD environment to verify the ability of an artillery firing battery to provide self-defense and protection in the firing position area and to perform the firing task when different types of adversary attack the firing position area. The objective of the experiment is to verify the ability of the artillery battery to survive within the Artillery Reserved Areas/Artillery Maneuver Areas (ARA/AMA) while performing combat tasks and the necessity of allocating additional resources (equipment, personnel, material) to protect and defend the firing position area and the artillery firing unit assets operating within it. The experiment results are the initial basis for follow-on simulations that will assess the impact on the ability to accomplish an artillery battery operation’s planned and unplanned joint fire support tasks.
