Hi,
For E-5 and below, you should qualify for food stamps, WIC, etc.
I do not know which branch of service or which base you are located, but go to the Navy Relief office. Sometimes, they are able to help in matters or direct you where to go.
Also, contact some of the service organizations such as DAV, VFW. If you served overseas, other organizations maybe available to help.
Does the base you are out of have a financial office to assist soldiers?
If so. contact them for other resources in the community.
You can also contact 'Military One Source' for assistance. I do not have the number handy, but you can go on the internet and get it.
I wish you the very best.
