Family Readiness Information

The primary source of unit/battalion information for spouses AND parents is the Deployment Readiness Coordinator (DRC) and Unit Hotline. The DRC will work with FR Assistants, FR Advisors and FR Volunteers along with the senior command members to make up the new Family Readiness Command Team.
