G-2 Intelligence




The DCS, G-2 is the Director of the Operational Environment Enterprise (OEE) and author of the Army’s approved current Operational Environment (OE). The TRADOC DCS, G-2 develops, describes, and delivers the OE in order to support the Army’s preparations to fight and win the nation’s wars.

Lines of Effort

  • Continuity of the OE Narrative
    • There are core OE narratives that describe the changing and complex conditions the Army will face whether we have a mission next month, next year, in 2035 or beyond. While users may need different aspects of the OE and they may require a specific OE time frame, there is continuity in our dynamic OE narrative over time that can withstand the most rigorous external scrutiny. That narrative is in two documents. G-2 TRADOC’s OE estimate provides discussion of near-term elements while our The OE and the Changing Character of Future Warfare paper looks deeper into the future.
  • Critical Thinking
    • The Critical Thinking Enterprise (CTE) is essential to help us constantly review and refresh our understanding of the OE. The CTE trains Army leaders to think critically about the OE and reaches out to academia, industry, and government.
  • Data Centricity
    • The OEE must enable the delivery, application, and use and reuse of information. Our OE must be timely, accurate, relevant, and predictive. It must also be digitized so that it is readily discoverable, retrievable, and usable by our many users.
    • Organizational Capacity and Resources
      • To achieve mission needs and priorities the OEE must be able to provide all support and sustainment activities areas of resource.

The TRADOC G-2 ACE develops TRADOC’s Operational Environment (OE) and produces a narrative rooted in Intelligence Community assessments and augmented by unique inputs from partners across the Army, Joint Community, the government, industry, and academia. This robust OE, which spans the present through 2050, is applied to support Leader Development, Training, and Education (LDT&E), and Concepts and Capability Development. The ACE Chief leads one of three TRADOC G-2 lines of effort, “Maintaining Continuity of the OE Narrative” and ensures OE support to the Army, TRADOC, and Army Futures Command. The ACE is comprised of four directorates: 


ACE Threats Directorate is the Army’s lead to study, design, document, validate, and apply Hybrid Threat and Operational Environment Conditions in support of LDT&E via the Threats Integration Branch (ACE-TI) and the Global Cultural Knowledge Network (GCKN). The Decisive Action Training Environments, Worldwide Equipping Guide (WEG), and hybrid threat products authored and maintained by ACE Threats are available via the OE Data Integration Network (ODIN).

ACE Futures Directorate studies the OE and threats through 2050 to inform concepts, capability development and testing via the Capability Development & Experimentation Branch, Wargaming and Concepts Branch, Capabilities Development Scenario and Studies Directorate (CDSSD), and the Mad Scientist Program. TRADOC G-2 Mad Scientist is a TRADOC initiative and a community of action that continually explores the future through collaborative partnerships and continuous dialogue with academia, industry and government.

ACE Fusion Directorate integrates research and analysis efforts from across the ACE with those of the Intelligence Community to produce tailored assessments for senior leaders within the Army and Department of Defense and provides direct support to TRADOC G-2 Operational Environment Center (OEC) training and exercises. The Network Engagement Team trains members of the joint, interagency, intergovernmental, and multinational (JIIM) community focusing on integration of social network analysis to improve understanding of the friendly, neutral, and adversarial networks that exist within the OE.

Foreign Military Studies Office (FMSO) researches, discovers, and describes open source, foreign perspective insights of understudied and unconsidered aspects of the operational environment. FMSO’s publishes books, monographs, and papers are integral to critical thinking in the Army’s leadership, analytic communities, and military education, and wherever there is a professional interest in what “they think they think.” FMSO’s Operational Environment Watch provides translated selections and analysis from a diverse range of foreign articles and other media that our analysts believe will give military and security experts an added dimension to their critical thinking about the Operational Environment.
