The only positive thing to this story is that most of the aircraft and vehicles we left behind were older versions that we would have scrapped anyway if we had kept them. None of our cutting edge top of the line equipment was given to the Afghan government.
I worked with some guys who were contractors and went to the Middle East various times to do maintenance on military equipment. They had numerous amusing stories about the mechanical backwardness and carelessness and laziness of the people there. I expect much of the equipment will be unusable soon if it isn’t already.
Almost all the equipment was made for counterinsurgency. The worst loss I think were the helicopters.
There were many stories about the loss of lots of the latest versions of NODs and other night fighting equipment. A good set of Gen III NOD binoculars can run around $10K each.
The afgans are trying to sell a surveillance blimp that had latest radar to Iran. It was used for tracking low flying missiles.
