This training circular (TC) outlines a methodology for designing and executing training exercises. It describes planning procedures and methodologies, responsibilities, and analysis for those who plan and control Army exercises intended as culminating collective training events that critically assess unit-training status. Collective training is part of unit training. It is performance oriented and a command responsibility executed by leaders at all echelons. As a continuous process executed in accordance with a formal training program, collective training trains units and teams on tasks and missions they are expected to perform. It is executed in a crawl-walk-run approach and reaches across all training domains and integrated live, virtual, constructive, and gaming training environments. This publication applies to the Active Army, the Army National Guard (ARNG)/Army National Guard of the United States (ARNGUS), and the United States Army Reserve (USAR) unless otherwise stated. Headquarters, U.S. Army Training and Doctrine Command (TRADOC) is the proponent for this TC. The preparing agency is the Contemporary Operational Environment and Threat Integration Directorate (CTID), TRADOC G-2 Intelligence Support Activity (TRISA)-Threats.
