Whoa, Major Z. Thank you for all of the research you did and are still doing. Please keep posting the results! Meanwhile, here’s an armband that most people would “write off” as non-US:

 

 

However, the two Korean letters under the words “ROK Marines” are “Guide” and under that the wording translates to “Northern California Marine Veterans Association”. So, some type of Marine veterans tour group visiting South Korea.

FB pic showing to MP arm bands being worn during the WW1 time frame. Sorry the descript is cut off, but it is pretty interesting if you want to look it up yourself and read more about it.

This armband is for a Marine unit, the Truck Company of the 3rd Division Support Group:

 

Nicely embroidered Corps of Engineers armband, but no idea of its specific function:

 

Well, this is reaching a bit, this is from “Call of Duty”:

 

Here is an interesting one I just saw on ebay. 91st INF on an orange arm band. Not sure what this signifies or its purpose. Something for training? Observer controller? 

I just saw this on eBay.  I had never heard of a coutesy patrol so I looked it up on the Internet and found this definition:

 

 "Uniformed Soldiers conducting courtesy patrols will approach off-duty Soldiers, Sailors, Marines and Airmen who are conducting themselves inappropriately, confirm their identities and encourage the service members to modify their behavior."

Did Courtesy Patrol on a Saturday night on Okinawa in 1970 in Koza. It was me, a SP4, with a SSG. We wore simple brassards with just "CP" on them. Not something I'd want to do more than once.

This is a bringback from a guy who was an advisor to the Interim Security for Critical Infrastructure (ISCI) agency. Marjah is a village in Helmand Province, Afghanistan. The program of Auxiliary Police was started in 2010.

 

Saw this one on the Internet somewhere (on maybe on here, unfortunately, I don’t know). It’s a cool one:

Hi Cobra 6.

 

Thank you for keeping this thread running which our forum friend SABREJET ( Ian Phillips ) started.   Today would have been Ians 71st birthday, his wife Sian has just sent me the following photograph of her visiting one of their favourite spots and where a brass plaque commemorating Ians life sits.

Very nice armband Cobra 6, what era is this from?

It is from the 1950’s to early 1960’s, jmd62. Thanks for asking.

Estate sale find with Army and Marine items. Anyone able to identify ? 

Just an educated guess, but some military police units did use the term “Highway Patrol” for traffic enforcement duties. It even carried over to the countries we advised, such as Iraq:
