A Deployment Allowance is a financial benefit provided to military personnel when they are deployed away from their home station. This allowance helps cover additional expenses incurred during deployment, such as housing, food, and other necessities. It is designed to support service members and their families during the time they are away from home. The amount of the deployment allowance can vary based on factors like the location of deployment and the length of time spent away. It is part of the broader set of benefits available to military personnel, which may also include Basic Allowance for Housing and Combat Zone Tax Exclusion.
