Navy people needed in Denver to attend the funeral for a Navy vet who was a recluse

Hello all. I'm the executor for my ex-boyfriend. Recently, he was discovered in his home after lying there dead for at least a year and a half. Needless to say, he was a very reclusive person. Wonderful guy, though. His will specifies a military funeral in a veterans cemetery. I am probably choosing Fort Logan, which is in Denver. I don't know yet when the funeral will be, but I'm assuming sometime this month.

It will break my heart if it's just me sitting there at his funeral. He deserves to be honored. He would have loved it if some Navy brothers and sisters, either active duty or veteran, came to the funeral with me. Service animals very welcome because my ex's passion in life was animals. Do you know of any organizations I can reach out to in order to make it happen?
