North Yemen patch and (Egypt?) special forces badge

Very nice pieces, thanks for sharing.
The shield patch is indeed from North Yemen, with the single star, and says War College. It is identical to the Egyptian/UAR War College patch worn by students during the 1960s-1970s.
The arc is nice - the cut-out letters reflect better quality manufacture compared to stamped examples. It’s a little hard to read but the first word (on the right-hand side) might say “Sa’iqa” (commandos), and the second word (on the left) probably says “al-amn” (security).

Thanks for the information, very interesting. The arc pin was listed as Iraqi from post Ww2 period however I have a friend who said it was most likely Egyptian. I paid about 9 usd for the patch and 2 usd for the pin so I am still happy with my purchases
