If you talk to him I'd be interested in hearing where he got them. I know, for a fact, Ft Bragg BX comics didn't contain the MJ inserts from 1986-on...
You rarely see MJ inserts in any bulk even around military bases. I've scoured back issues around military bases in NY (Fort Drum), NC (Bragg and Seymour), SC (Shaw and Charleston), FL (Jacksonville, Pensacola, Eglin, and Hurlburt), Georgia (Moody and Hunter), Virginia (Norfolk and Langley), TX (Hood and Bliss) and Mass (Hanscom). The only places I found MJ inserts in any stock at all was Pensacola and Charleston. And even then it wasn't much...
The only times I've gotten MJ inserts in bulk was in buying collections from indivduals previously assigned overseas or from German dealers selling US comics...
