"Extra!" Using the Newsvendor Model to Optimize War Reserve Storage

The United States Marine Corps (USMC) Installation and Logistics Command requested a study for determining appropriate inventory levels of war reserve materiel to meet future operational needs under surge demands in uncertain environments. This study sought to explore a potential approach by using the common newsvendor model, but modified for a military scenario. The authors’ novel version of this core concept considers the purchase and storage costs of an item and proposes an intangible cost function to capture the consequences of a shortage. Further, they show a sample application of the model using a ubiquitous military item—the BA-5590/U battery. The output of the model provides USMC with a new tool to optimize inventory levels of a given item of interest, depending on scenario inputs.

HEDGEMONY: A Wargame to Evaluate Senior Joint Professional Military Education Learning Objectives

The Officer Professional Military Education Policy directs Joint professional military education institutions to develop officers who demonstrate critical and creative thinking skills. The chairman of the Joint Chiefs of Staff ’s intent is to develop strategically minded officers who will “creatively apply military power to inform national strategy, conduct globally integrated operations, and fight under conditions of disruptive change.”1 The wargame Hedgemony is unlike most other wargames. Its focus is on teaching defense professionals how strategies are a complex interaction between force development, force posture, and force employment. Hedgemony also provides a way in which the Marine Corps War College measures its program outcomes.

PROMISE UNFULFILLED: A Brief History of Educational Wargaming in the Marine Corps

This article offers a comprehensive historical overview of educational wargaming in the U.S. Marine Corps and how it can evolve in the future. The tradition of leveraging wargames for educational and training purposes is deeply rooted in the Marine Corps. From humble beginnings at the Naval War College to Service-wide wargaming initiatives like TACWAR, the Marine Corps has always sought to develop the intellectual edge of its Marines through wargames. Yet, in successive decades, the Marine Corps has consistently struggled to maintain its wargaming efforts. This article concludes with recommendations on how to develop, expand, and evolve educational wargaming in the Marine Corps.

DEVELOPING SELF–CONFIDENCE IN MILITARY DECISION MAKIN: An Imperative for Wargaming

In his Commandant’s Planning Guidance, the 38th Commandant charges the Marine Corps with doing more to employ wargaming in education and training. It is not often clear why the Marine Corps needs to use this technique to practice decision making, given other kinds of decisions games, such as tactical decision games (TDGs) and decision forcing cases (DFC). While these other decision-making educational tools have their advantages in honing the communication of estimates, orders, and corresponding rationales, the primary virtue of wargaming lies in the far larger number of decisions players must make in a continuously unfolding situation.
