Department-Level Exercise (DLE) Series 

Through this series, the Department of the Air Force is preparing to be a stronger, more lethal deterrent force, to provide an advantage against competitors and adversaries across all domains, and to ensure regional stability in the Indo-Pacific and beyond. 

 

The DLE series will incorporate multiple command exercises into one overall threat deterrence scenario, including Resolute Force Pacific (REFORPAC), Resolute Space, Mobility Guardian, Emerald Warrior and Bamboo Eagle 25-3.  

It will also integrate multiple allies and partners in specific component exercises with shared interests. Partner integration is critical to U.S. efforts to ensure regional and global peace and stability and provides a decisive advantage against complex threats.

Part 1 of 4: The roots of the First World War grew in Balkan tensions, nationalism, imperial rivalry, regional conflicts, and a tangled system of alliances. These factors directly contributed to the outbreak of WWI and its rapid spread across Europe. This documentary sheds light on many of the causes of one of the most significant conflicts in modern history. The assassination of Archduke Franz Ferdinand in 1914 by a Serbian nationalist served as the spark that ignited the European powder keg. Austria-Hungary declared war on Serbia, triggering alliances – Germany backed Austria-Hungary, Russia backed Serbia, and soon France and Britain joined against Germany. This quickly escalated into a continent-wide, then global, conflict. Like, comment, and subscribe!
