This guide provides an overview of the Joint Training System(JTS) and highlights the role of senior leadership in the planning, execution, and assessment of joint training. The JTS is the command's training system. In broad terms, the JTS is designed to ensure the U.S. Armed Forces are trained and prepared to counter violent extremism, deter and defeat aggression, and strengthen international and regional security. More specifically, it provides a capabilities-based method for aligning training programs with assigned missions (GEF, GFMIG, JSCP, and UCP) consistent with command priorities, capabilities (both current and proposed), and available resources (TCP/CSP). The Joint Training Information Management System (JTIMS) is a Web-based tool suite that, in conjunction with the Defense Readiness Reporting System (DRRS) and the Joint Lessons Learned Information System (JLLIS), provides a set of integrated information management capabilities to identify, collect, analyze, store, and disseminate the data required to support implementation of the JTS and sustain a command joint training program.
