Hi Mike
Yes, I've seen these on ebay for a while now. At best they are prototypes or drafts of a badge never adopted. The seller has had some JTF2 badges, as well.
I have a copy of those draft Combat Action Insignia rqmts and a blank nomination/application form somewhere on a stick that I was complete on my Platoon in Afg in '07. They got filled out but never sent in. Deleted.
Would have resulted in two or 3 of the troops getting bronze for being close enough 122mm rocket impacts. We weren't a combat force!!
regards
Darrell
