When they do face the M-1 tanks, they were outgunned and outmatched. Even the British Challengers were superior.
Its like Shermans versus Panthers / Tigers...
But unlike in the WW2 allies, the Iraqi's resources were quite limited.
Saddam - Built cheap and lousy bronze stature that was easily torn down.
Qin Shi Huang - Built the Great Wall of China and is visible from space. Still standing today and is making money as a tourist attraction.
Saddam - 0
QSH - 1
hehe, just joking
by the way, since you mentioned it...
The Great Wall being seen from space...is just a legend, it is actually cannot be seen from space with naked eye.
Seen from space, it is just a line without thickness. When I checked Google Earth about 2yrs ago (when the images are not detailed as they are now), all I can see is mountain and were not able to detect any trace of the Great Wall.
Besides, the pieces of the Great Wall that Qin Shi Huang built mostly ruined already, most of the Great Wall nowaday is contributed by a lot of others. He event was not the one who built it first, he connected smaller pieces.
Qin Shi Huang - Great Wall of China.
Saddam Hussein - Great Depression of Iraq
