H.R. 2200 amends Coast Guard law to require the retention of enlisted service members who are close to qualifying for retirement benefits. Specifically, regular Coast Guard enlisted members who face involuntary separation or reenlistment denial within two years of their 20-year retirement eligibility must be kept on active duty until they reach retirement qualification. Reserve members with 18-20 years of service receive similar protections but with some flexibility—those with 18-19 years of service can be separated only with their consent or after three years (whichever comes first), while those with 19-20 years of service have a two-year window. The bill does not specify funding amounts or implementation deadlines. The legislation aims to ensure that Coast Guard personnel who have invested nearly two decades of service are not discharged before becoming eligible for retirement benefits.
