  planning and analysis, and specialized training to assist units in garrison, during exercises, and during
  contingency operations.
  3-23. 1st IO Command also supports the Army by working to optimize IO interoperability with joint forces,
  other military forces, inter-agencies, and allies. It provides expeditionary cyberspace operations support to
  help units identify network vulnerabilities and enable IO.
  Deployable Modular IO Teams
  3-24. Deploys a variety of mission-tailored IO and cyberspace operations teams. The configuration of each
  deploying team varies to meet operational requirements.
  Field Support Team
  3-25. Provides IO subject-matter expertise to supported commands to assist with the planning, execution and
  assessment of IO during crisis, contingency, and exercise operations. Field support team members are trained
  in the operational integration of military deception, electronic warfare, MISO, OPSEC, cyberspace
  operations, and other activities impacting the information environment.
  Vulnerability Assessment Team
  3-26. Assists supported commands in identifying and resolving IO and cyberspace vulnerabilities in order to
  improve the command’s defensive posture. The vulnerability assessment teams deploy to provide either:
  Train and Assist (Blue Team) or Emulation of an Adversarial Attack (Red Team) support. Both are capable
  of assessing the supported command’s OPSEC, physical security, and electronic security training and policies
  to identify vulnerabilities. Both vulnerability assessment teams also assist the supported command in
  identifying IO and cyberspace vulnerabilities tied to issues associated with unit procedures, equipment, and
  other resources, and in finding means to resolve or mitigate identified issues. In addition, the vulnerability
  assessment teams augment the U.S. Army Forces Command mission command assessment teams in
  conducting pre-deployment home station cybersecurity training, as well as execute the Command Cyber
  Readiness Inspections for Army Cyber Command in coordination with the Defense Information Systems
  Agency.
  OPSEC Support Team
  3-27. The OPSEC support team is part of the 1st IO Command organizational structure, and augments
  vulnerability assessment teams and executes independent OPSEC support team missions. OPSEC support
  teams provide supported commands with OPSEC training, assist with developing OPSEC programs, and
  assess unit OPSEC programs.
  World Class Cyber Opposing Force
  3-28. Provides cyber and information warfare opposing force support to designated commands during
  operational training events, such as major exercises and combat training center rotations. This force serves
  as a non-cooperative, multiple tier (criminal, hybrid, nation state) cyberspace threat opponent that challenges,
  trains, and develops leaders to successfully operate within a hostile information environment. The World
  Class Cyber Opposing Force executes its opposing force mission as the exercise dictates, and will operate
  either as an independent force or as a member of a larger opposing force.
  Reachback and Training Support
  3-29. Provides IO planning support, intelligence analysis, and technical assistance to deployed 1st IO
  Command support teams, and to other commands requesting reachback support. Reachback tailors its
  analytical and intelligence efforts and products to support the current and future operations of the supported
  commands. Lastly, the reachback provides technical support for the execution of vulnerability assessments
  and World Class Cyber Opposing Force missions.
  3-30. The 1st IO Command conducts training instruction throughout the year on the planning, integration
  and execution of IRCs in both a resident (at Fort Belvoir) and mobile training team format. The 1st IO
