There are many different types of Veterans’ benefits from employment, finances, housing to memorialization.  To access benefits, different eligibility factors are considered such as service history, medical need, income level.
In order to determine the benefits you may be eligible for due to your military service gathering your DD 214, your military history with the branch of service you participate in, and any medical information related to your military service will be helpful.
In Maine, the Department of Defense, Veterans and Emergency Management, Bureau of Veterans Affairs is a place to start.  You can contact the Bureau at 207-430-6035 or on-line at https://www.maine.gov/dvem/. or download the Welcome-kit at: https://www.va.gov/welcome-kit/.
