This bill amends title 14, United States Code, to ensure the retention of certain enlisted members of the Coast Guard who are nearing retirement eligibility, preventing their involuntary separation. Its primary purpose is to protect members with significant service who are close to qualifying for their full retirement benefits. For Regular Coast Guard members , the bill mandates that any enlisted member facing involuntary separation or denied reenlistment, who has completed 18 or more, but less than 20, years of service, must be retained on active duty until qualifying for retirement. Similarly, Coast Guard Reserve members in an active status with 18 to 20 years of service, facing involuntary separation or denial of reenlistment (not for cause or disability), cannot be discharged or transferred without their consent. This protection ensures they can complete their 20 years of service, or until a specified anniversary date, to secure their retirement benefits.
