Assessing Risk At The National Strategic Level: Visualization Tools For Military Planners, Wade A. Germann, Heather S. Gregg
Assessing Risk At The National Strategic Level: Visualization Tools For Military Planners, Wade A. Germann, Heather S. Gregg
The US Army War College Quarterly: Parameters
The reemergence of great power competition, conflict with near-peer competitor states below the level of armed conflict, and persisting threats from nonstate actors with transnational ambitions and global reach pose challenges for strategists planning, executing, and assessing military operations and strategy. Building on current visualization tools, two proposed models—the National Strategic Risk Abacus and the National Strategic Risk Radar Chart—address these challenges and better depict how the US military may inadvertently contribute to risk at the national strategic level.

Hope Versus Reality: The Efficacy Of Using Us Military Aid To Improve Human Rights In Egypt, Gregory L. Aftandilian
The US Army War College Quarterly: Parameters
Using US military aid as a lever to achieve human rights reforms has proven only marginally effective. This article examines the approaches employed by the Obama and Trump administrations to US military aid to Egypt and proposes practical steps that can be taken by policymakers and the military personnel on the ground to advance US human rights values.
The Evolution Of Hybrid Warfare: Implications For Strategy And The Military Profession, Ilmari Käihkö
The Evolution Of Hybrid Warfare: Implications For Strategy And The Military Profession, Ilmari Käihkö
The US Army War College Quarterly: Parameters
The concept of hybrid war has evolved from operational-level use of military means and methods in war toward strategic-level use of nonmilitary means in a gray zone below the threshold of war. This article considers this evolution and its implications for strategy and the military profession by contrasting past and current use of the hybrid war concept and raising critical questions for policy and military practitioners.

Creation Of A Cip Method For The Heat Exchangers At Rolls-Royce, Melanie Howe, Austin Williams, Caroline Dempsey, Bethany Fralick
Journal of the South Carolina Academy of Science
Rolls-Royce produces various engines which must be tested prior to their distribution to ensure a high-quality product. The manufacturing plant contains four test cells where the engines can be subjected to high levels of torque and extreme temperatures. A heat exchanger is necessary in this testing system and over time, unwanted waste accumulates on the system’s plates. The team is tasked with developing and implementing a system mounted on a mobile cart which can provide data to determine whether the plates need to be cleaned. For this cleaning system to work, it must fully saturate the heat exchanger in cleaning …
