Final answer:
The Navy Good Conduct Medal (NGCM) can be awarded up to 3 months prior to the eligibility date for first-term Navy personnel who meet all other eligibility requirements.
Step-by-step explanation:
For first-term personnel in the Navy who meet all eligibility requirements except length of service, the Navy Good Conduct Medal (NGCM) may be awarded up to 3 months prior to the eligibility date if the member is discharged or released to inactive duty. This early award is intended to recognize the individual's good conduct during their service even if they are leaving the Navy just short of the official service period required for the award normally.
