Our soldier writing home appears to be wearing ripstop ERDL. As he is a private, he is not a member of Special Forces, so it would be interesting to know what unit he was with to be authorized such a uniform. His helmet cover looks older than he is.
you owned the day with your show ! I have this booklet and some others. I picked them up in a Recruiting Station in New Jersey in 1981. There is one with a well decorated 173rd Abn vet NCO counselling young civilians.
About the soldier in ERDL, the answer might here on an another USMF thread, where else ?!
