[Editor’s Note:  Army Mad Scientist is pleased to publish its 500th post!  Since its inception on 09 November 2017, the Mad Scientist Laboratory has continuously sought to explore the Operational Environment (OE) and the changing character of warfare on behalf of the U.S. Army.  Given this enduring mission, it’s fitting that this milestone post features the highlights from our latest episode of The Convergence podcast.  Army Mad Scientist sat down with Mr. Ian Sullivan, Deputy Chief of Staff Intelligence (DCSINT) G-2, U.S. Army Training and Doctrine Command (TRADOC), to discuss the TRADOC G-2’s newly published The Operational Environment 2024-2034:  Large-Scale Combat Operations.   The OE underpins how the U.S. Army is organized, trained, equipped, and operates — it is foundational in ensuring the Army’s mission success — fighting and winning our Nation’s wars.  This latest OE assessment focuses on how our adversaries are learning and adapting how they fight from recent and on-going conflicts around the globe (e.g., Nagorno-Karabakh, Ukraine, Gaza, and the Gulf of Aden).  It describes the twelve conditions that contribute to Large-Scale Combat Operations (LSCO) and five resulting implications for the U.S. Army.  This new OE assessment is central to how the U.S. Army integrates the threat within our Leadership Development Training and Education system, our doctrine, and our modernization efforts across the DOTMLPF-P spectrum of capabilities.  In preparing for LSCO against our pacing and acute threats (China and Russia, respectively), it represents the “gold standard” for which the Army must ready itself as a “precursor to victory.”  Any and everyone associated with defending this great Nation should familiarize themselves with its contents — Read on!] Mr. Ian Sullivan is the Deputy Chief of Staff Intelligence, G-2, TRADOC.  He holds a BA from Canisius University in Buffalo, New York, an MA from Georgetown University’s BMW Center for German and European Studies in Washington, D.C., and was a Fulbright Fellow at the Universität Potsdam in Potsdam, Germany.  A career civilian intelligence officer, Mr. Sullivan has served with the Office of Naval Intelligence; Headquarters, U.S. Army Europe and Seventh Army; the Office of the Director of National Intelligence (ODNI) at the National Counterterrorism Center; the Central Intelligence Agency; and TRADOC.
