There aren’t a ton of veterans here but maybe someone will see this.
Also, I know this is for Charlie Company, but perhaps this website will lead you to some contacts: http://www.c-1-8-4th-id.com/
There was (and maybe still is) an organization for A/1/8/4th Inf but their website is no longer up and running. I really hope the above link helps you out.
You can also email me with contact information in the event anyone replies to this: email@example.com
