Gino is pretty much spot on with respect to the tarmac at Mog International. I spent a little time in Somalia (5 1/2 months) and can tell you this...you could see that at one time, Mogadishu in particular was a beautiful city. Picture that and then picture the movie Road Warrior. I don't remember a single structure that had not been blown up, shot up or burned up is some way. The streets were apocalyptic with moounds of drifting dirt, etc. Picture junkyards all over and shanty towns of huts with corrogated tin. It was like you went to another world.
So, you can see that yes...there were at one time some pretty nice airfields. But during JTF Provide Relief, JTF Restore Hope, UNISOM and Gothic Serpent (which was the entire operation that TF Ranger deployed for), the airfields in Somalia ran the spectrum of pretty nice (Mog) to austere dirt strips with maybe some prefab matting. At one time some of these military strips/airfields had been fairly nice but they really went to hell during and after the civil war and famine. You could do your diorama however you wanted. A dirt covered strip (red dirt) like Bardera or even Baido or Giallassi. Or semi nice like Kismayu (concrete parking pad, but still pretty dirty (if Kismayu, you could even include the old Ethiopeon Canberra that was sitting off to the side of the ramp). If Baidoa, you could even do the control tower which was built out of wood scraps on top of a copuple shipping containers. You could even do the AH-1W & UH-1N QRF birds sitting on the side when the Marines had security there (Baidoa) before the Aussies took it over. I vividly remember the talcom powder sand/dirt at Belet Uen where the Canadian parachute regiment were based. I always made it a point to do some ration swapping with them...shepards pie, yum, yum.
Whatever you do, make her dirty. Just about every Herk I remember was stained to varying degrees with that redish dirt that I became some dang fond of.
Or, you could have them parked on the prestine ramp that they operated out of at Nairobi. I always wondered about that. All the other Herks operated out of Mombasa (USAF, Belgians, USMC tankers, Southern Air Transport, Swedes, Brits, GAF Transalls, Kiwi Andovers), but the Canadian Herks operated out of Nairobi....go figure.
I feel like a goob for asking but avgp markings????
