From Recruit Training Command - 14 August 2020

Beginning August 21, U.S. Navy Recruits will spend 14-days in a restriction of movement (ROM) status at Fort McCoy, a U.S. Army training center in western Wisconsin, before being transported to Recruit Training Command (RTC) in Great Lakes, Illinois, to begin training.

In July, RTC increased shipping to over 1,200 recruits per week. To accommodate the increased volume of recruits, ROM is taking place at multiple Gurnee, Illinois, area hotels. Moving ROM to Fort McCoy ensures long-term safety and security of recruits, consolidating support staff in one location, and ensures RTC’s perpetual effort to be good stewards of government funds while continuing to execute the essential task of training the Navy’s newest Sailors. RTC continues to protect the welfare of its recruits and staff and continues to work with medical experts to ensure it can train while responding to and preventing transmission of the coronavirus.
