No idea; it’s the only photo I’ve been able to find of a Yemeni Hind where the roundel is clearly visible.

No problem.

You might also be interested in this; I was reading the November 2001 edition of AirForces Monthly and found this YAF L-39. You can sort of make out the Emblem on the fuselage of it, and this photo would have been taken in 2001 or earlier.
Also attached are two photos of YAF L-39s photographed at Ukraine in 2006, with the Emblem much more visible.

I hope this is of interest!

New roundel for Yemen

I’m unsure if you meant new as in post-unification, or new as in post-revolution, but that roundel has been in use since the late-2000s prior to the revolution.

Here it is on a MiG-29; source Hot Skies Over Yemen Volume 2 by Tom Cooper.

Here’s a real head scratcher; this flag can be seen from a distance for all of a few seconds from a handful of shots in one scene in the 2015 movie No Escape. I had to pause the movie for almost an hour to scrounge around trying to find information on it, but it seems it was designed for the sole purpose of a few angles in this scene. Would’ve been easier to have just not included a fictional flag, frankly.

Looks like some sort of hybrid between the Bhutanese dragon and Sri Lankan lion? You can see the design mirrored in black behind the door.

The helicopter is a MBB/Kawasaki BK 117 with the registration HS-SFB, the registration belonging to a helicopter of Si Chang Flying Service (SFS) out of Thailand, where the movie was filmed in. I’ve included it in it’s Thai colors. airport-data.com lists the helicopter as having been sold to New Zealand shortly after filming of the movie.
