Disability Retirement Pay is a monthly payment given to veterans who meet the disability requirements due to events that occurred during service, and to veterans whose service made an existing condition worse. If you have a condition like PTSD or other chronic illnesses and injuries, you may qualify for these disability benefits. The pay is offered through Veterans Affairs (VA) and the amount is based on your disability rating with the VA. You can’t combine disability pay with a VA pension, but you’ll be paid whichever is the higher amount.
