DLA is a flat sum given to U.S. military members and their families to help cover any incidental or extra expenses that are incurred when moving during a PCS.
The specific DLA amount a service member is entitled to is based on pay grade and dependent status. Some military members may also be entitled to a Secondary DLA, which is available for individuals whose PCS or move orders change after they've already relocated.
