Solving partially observable agent‐intruder games with an application to border security problems

In this paper, we introduce partially observable agent‐intruder games (POAIGs). These games model dynamic search games on graphs between security forces (an agent) and an intruder given possible (border) entry points and high value assets that require protection. The agent faces situations with dynamically changing, partially observable information about the state of the intruder and vice versa. The agent may place sensors at selected locations, while the intruder may recruit partners to observe the agent's movement. We formulate the problem as a two‐person zero‐sum game, and develop efficient algorithms to compute each player's optimal strategy. The solution to the game will help the agent choose sensor locations and design patrol routes that can handle imperfect information. First, we prove the existence of ?‐optimal strategies for POAIGs with an infinite time horizon. Second, we introduce a Bayesian approximation algorithm to identify these ?‐optimal strategies using belief functions that incorporate the imperfect information that becomes available during the game. For the solutions of large POAIGs with a finite time horizon, we use a solution method common to extensive form games, namely, the sequence form representation. To illustrate the POAIGs, we present several examples and numerical results.

The rise and fall of counterproliferation policy

The US government initiated a Defense Counterproliferation Initiative to address the concern that, in the post-Cold War years, the proliferation of nuclear, biological, and chemical weapons would be widespread and create a significant challenge to the US military’s combat operations. In particular, non-nuclear states might use chemical or biological warfare agents against US forces with the belief that nuclear weapons would not be used against them in retaliation. Following the events of September 11, 2001, defense strategy and policy shifted to a wider view of the threat of adversarial use of “weapons of mass destruction” (WMD) and the term “counterproliferation” was replaced by “combating” or “countering WMD.” Over time, the Defense Department increasingly moved away from counterproliferation principles with the detrimental effect of losing capabilities that US forces still need for contemporary adversaries. This shift has been aggravated by other US government agencies’ use of “counterproliferation” in lieu of what would have been termed “nonproliferation” activities in the 1990s. The loss of clarity within the US government on these terms has led to the inability to focus the “whole of government” on this significant national security challenge. To alleviate this challenge, the US government needs a top-down initiative to refocus policy on the distinctly different aspects of WMD with respect to military combat operations, combating terrorism, and homeland security.     

Sharing the load: factors in supporting local armed groups in insurgencies

Most counterinsurgency campaigns have featured the use of some form of local defense forces. Such forces have had a somewhat mixed record, both in their usefulness in actually countering insurgents and in their longer-term impact on internal security. This article focuses on historical cases that provide lessons for the best operational and strategic uses of local defense forces and measures to control their activities.

Challenges of institutional coordination in complex defense acquisition programs: the case of the Republic of Korea’s F-X program

Decision-making in defense acquisition programs in the Republic of Korea (ROK) has been problematic, especially in highly advanced complex systems. The highly disputed force modernization program for the ROK Air Force’s fifth-generation fighter, dubbed the Fighter eXperiment, went through extreme turbulence during the type selection phase. The gist of the turbulence became evident through poor institutional coordination within the defense acquisition authorities that eventually forced them to rescind the decision generated from their own yearlong efforts, thus basically shooting themselves on the foot. The paper highlights the background of the program and reviews the institutional elements that influenced the decision-making process, and conclude that the absence of an effective coordination mechanism has made decision-making in complex defense programs even more troublesome.
