Speak with a vets rep if you served within a period of conflict such as VN. The VA will pay an additional pension if you qualify within certain time periods and meet aditional requirements. It is called a non service connected pension, less than a full pension but more than SS. The currant VA non service pension is $824.00 per month, they will add to your currant SS payment until you recieve the $824.00.
When working with the VA have patience, they have a large workload to handle and it takes years in some cases. You do not have to have combat experience to qualify for the non service connected pension.
