Have you tried a VA Hospital or clinic near you or Google for a group you are trying to get.
Take little steps and you will get the help.
You raise a question I'm asked very often. Nationally, veteran's groups are generally available, locally one might find something listed in their newspaper but that medium is shrinking in the instant news cycle of social media etc. For first responders support is near non-existent, the video chat you describe is an alternative I had not thought of but would require some relationship building which is a good thing. My suggestion to those first responders who have called inquiring about (face to face) groups is to start their own and I explain what that would look like. I wish I had more to offer, if your aware of something I'm missing I look forward to hearing from you. Thank you for all your efforts in posting and educating on USFRA.
