Saw a lot of those in '91 while humping north. Then oddly enough I saw them all between '05 and '09 while working in Kuwait where they'd been dragged off to be lined up in the desert north of the airbase near al Jahrah. Just before I left country they'd started chopping the carcasses up to be sold as scrap. Guess the DU had decayed or blown away enough to interest a buyer.
Warthogs were like that old Timex watch commercial, 'It takes a lickin and keeps on tickin'.
Not many know this but the overall concept was modeled on the Ilushin Il-2 'Stromovik' of WWII fame. Basically a flying tank to kill tanks. Heavily armored to protect the pilot and a big honking gun screaming in at a few hundred km/h.
As always thanks for the great art.
