In what year was the requirement to perform 30 years of service for retirement changed?

The requirement to perform 30 years of service for retirement was changed in 1945. This adjustment was part of a broader effort during and after World War II to manage military personnel and encourage retention in a time when service members were vital to national defense. Prior to this change, the service commitment and retirement guidelines were different, and the 1945 adjustment reflected a shift in policy aimed at meeting the needs of the military amidst the backdrop of a significant conflict and its aftermath. The new guidelines recognized the contributions of service members and aimed to offer an incentive for long-term commitment by making retirement more accessible after a full 30 years of service.
