本文擬以西方「軍事革命」理論的角度，探討萬曆朝鮮戰爭時期，明軍薊鎮部隊的作戰表現。戚繼光「軍事革命」獨特之處在於，除訓練單兵作戰技巧外，亦重視部隊戰術隊型、協同作戰及指揮系統。從對抗倭寇時的步兵鴛鴦陣開始，至薊鎮抗虜時發展出步兵、騎兵、車兵、炮兵的協同作戰，是戚繼光「軍事革命」的主要元素。「戚家軍」戰鬥力之強勁，即根源於此。得益於戚繼光「軍事革命」的薊鎮部隊，是當時被成為「南兵」的主要部隊之一，在朝鮮戰場上更大放異彩，作戰表現遠勝明軍中的北兵。 / This thesis studies the performance of the Jizhen(薊鎮) Army during the Korean War (1592-1598) from the perspective of the "Military Revolution" theory. It argues that the Qi Jigunag revolutionized the training of the Ming army by focusing more on tactical formation, on coordination among different forces, on improving the commanding system, and also on more practical and united training of soldiers. As a result, the Ming army from Jizhen, also known as "the Southern Army", trained by the Qi Jiguang model, excelled in the Korean theatre by their military prowess and their good discipline and distinguished themselves from the more unruly and less competent Ming forces from the Northeast. / Detailed summary in vernacular field only. / 葉家銘. / Parallel title from English abstract. / Thesis (M.Phil.)

Approved for public release; distribution is unlimited / The United States is moving into a new era in which the enemy no longer provides symmetric opposition. The Navy and Marine Corps will face new challenges in the way they deploy and conduct future operations. One important way that these challenges will be met involves sea-based operations, which provide the sustainment necessary for prolonged operations and prevent unwanted operational pauses. Recent combat operations in Operation Iraqi Freedom (OIF) demonstrated difficulties when sustaining forces from logistics bases ashore. For example, advancing the Army and Marines to Baghdad in OIF consumed large amounts of fuel and ammunition. The resupply could not replenish supplies and an operational pause began on 29 March, 2003. In order to prevent operational pauses, rapid movement from the sea to the objective must be implemented. This thesis analyzes the problem of finding an optimal mix of Combat Logistics Force shuttle ships required to sustain the sea-base. This is accomplished through two optimization models: The first one determines a shuttle mix ensuring required inventory levels at the sea-base are maintained at all times. Since this requirement may cause some shuttles to be loaded partially, in the second model we manually assign the shuttle mix and then minimize unmet demand. This model yields a mix of shuttles that strikes a balance between shuttle cost and meeting sea-base demand. This thesis uses varying distances for conducting analyses over several scenarios. / Captain, United States Marine Corps

Approved for public release; distribution is unlimited / A "Bold Case for Unconventional Warfare" argues for the establishment of a new branch of service, with the sole responsibility of conducting Unconventional Warfare. The thesis statement is: Unconventional Warfare is a viable tool for achieving national security objectives under certain circumstances. Hypothesis One states that in order for UW to be effective it must be managed in accordance with specific principles. Hypothesis Two states that to optimize UW a new branch of service under the Department of Defense is required. Chapter II establishes the strategic requirement, laying the foundation by explaining the differences between UW and conventional warfare. Chapter III explains the requirements for dealing with substate conflicts. Chapter IV articulates the operational construct for UW revolving around an indigenous-based force in order for the US to gain influence in a targeted population. The second half of this thesis, Chapters V - VI, analyzes policy, doctrine, and schooling, as well as case studies of USSF efforts in the Vietnam War and El Salvador in order to reveal a conventional military aversion to the use of UW. The conceptual discussion of Chapters I thru IV supported by the research of Chapters V and VI together make "A Bold Case for UW." / Captain, United States Army / Major, United States Army

The war in Iraq is neither won, nor lost. To achieve US objectives in Iraq it is critical to understand not only the Iraqi Sunni components of the ongoing conflict, but also the Salafi-Jihadist elements as well. This thesis uses a social mobilization approach to study of the Salafi-Jihadi insurgent group, Al Qaeda in Iraq (AQI) describing the group's political opportunities, mobilizing structures, frames and repertoires of action. The result of this analysis shows an internationally-supported ideologically-motivated, militant group with few Iraqi-specific political or social strengths. This thesis applies this knowledge to established counterinsurgency methods to highlight organizational strengths and weaknesses in comparison to a normative counterinsurgency effort. This relational analysis views the conflict through a six dimensional framework to examine where the insurgents have significant strength and where they are vulnerable to counterinsurgency actions. We then examine the current status of the counterinsurgency operations and stabilization effort in Iraq. Trend-analysis tracks changes in key indicators through time underscoring areas for concern and areas of positive movement. Based on the nature of AQI and the current trends, this thesis will draw general conclusions and provide recommendations based on the AQI threat designed to undercut its strengths and exploit its weaknesses.

This thesis argues that a shift in the doctrine, organization, equipment and training of armies is required due to a shift in the nature of war. This thesis refers to the "new way of war" as Fourth Generation War (4GW) and this analysis is restricted to the army component of the defense forces. Armies at present are geared to fight the earlier generation of attrition and maneuver wars. In 4GW, an army structured for earlier generations of warfare is militarily dysfunctional. The thesis statement is: Infantry based armies practicing unconventional warfare (UW) are essential for the 4GW battlefield. The thesis argues for the conventionalization of UW. Hypothesis One states that heavy armor/artillery based armies should give way to infantry based armies. Hypothesis Two states that the military doctrine of these infantry based armies should be based on UW. The thesis explains 4GW and examines the relationship between terrorism and 4GW. It studies the impact of 4GW on the Principles of War. It examines whether Special Forces (SF) are the panacea for 4GW and whether increasing the size of SF is the solution. Lastly, the thesis discusses the changes required in the army to fight in a 4GW environment and provides recommendations.

Sand dune erosion is highly episodic occurring only when storm waves coincide with high tides generating swash that impacts the toe of the dune. Owing to the episodic nature of sand dune erosion, it is difficult to observe in nature. The removal of a structure and rip-rap sea-wall from the Stilwell Hall site located in southern Monterey Bay provided a unique opportunity to study erosion processes at an accelerated rate. A 1-D wave impact line erosion model (Larson et al., 2004) was tested against data acquired at this site between April, 2004 and April 2005. The model was optimally tuned to the data by a dimensionless coefficient that relates the impact force to the rate of recession. The coefficient values ranged from 0.7-1.3x10-3, for this field data, compared with values of 1.0-2.5x10-3 previously obtained for lab and field data. Migrating rip currents create a system of mega-cusps, which are nominally 10m in width and 200m in alongshore wavelength (Thornton, 2005). The presence of megacusps is hypothesized to accelerate sand dune erosion at their embayments where the beach is steeper and narrowest (Short, 1979;Shih and Komar, 1984;Revell, et al., 2002). It was determined that the highest recession occurred at the location of the rip current/mega-cusp embayment. Changes in the surf climate are of great interest to Naval Special Warfare (NSW) and U.S. Marine Corps (USMC) forces tasked with planning and executing operations in littoral areas. Naval history is replete with operations highlighting the importance of understanding and accurate prediction of nearshore dynamics. Without the ability to predict nearshore morphologic processes, providing such support is impossible.

CHDS State/Local / Adaptive terrorist organizational structure and the lack of intelligence sharing were to blame for terrorist attacks on September 11, 2001. Because terrorist groups are moving toward a less predictable, but more diverse, dynamic, and fluid structure, effective combativeness of terrorism requires fighting terrorists with a network. This network must be capable of collecting and sharing credible, reliable and corroborative information on an unprecedented scale, transcending geographic, agency, and political boundaries. This thesis demonstrates utilization of a network-theory approach for sharing information, which will be argued, can provide insight into the system dynamics of the U.S. IC because it allows a systematic, comparative analysis of the system representation and fundamental problems associated with information sharing. The problems associated with past intelligence failures can be overcome with such a system because the use of a dedicated, nationally networked system will allow completion of three primary tasks: (1) examination of the strength of criminal/terrorist connections, (2) identification of suspects and mapping of networks, and (3) prediction of future behavior and better likelihood of prevention, response, and prosecution. A dedicated national networked intelligence-sharing system called DNIN (Dedicated National Intelligence Network), including geographic areas, regional centers, personnel, computer IT networks, and policy options is discussed. / Scientist, U.S. Department of the Interior
