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.
