It would be rare for the us to give our most advanced or best appointed equipment to a force we were supporting. I’m unsure that the current administration would make that same choice but if it hardware is in the field somewhere in the world it is likely that china, Russia, and all other arms dealers and manufactures have the specs.
Popular Mechanics had an article that made the claim that indeed any tech left behind was nothing special. However, the sheer number of equipment for making war left was mind boggling and certainly very helpful to the Bidiban.
Biden's withdrawal was a complete disaster for this country. Leaving as many weapons behind as he did is impeachable. Biden was in charge and now he has effectively armed a very large terrorist force. The Taliban have not changed nor has Al Qaeda. There is an extremely high probability we will be attacked within our borders by terrorists. Biden has not only armed them and thrown the gate open for them on our southern border.
If the Taliban invite in the Russians, Chinese, and Iranians, those weapons will be closely scrutinized and reversed-engineered. Biden has given them the opportunity.
Didn't we leave the weapons behind for the Afghan military ? Now that I've learned more about what was happening inside Afghanistan with all the corruption, perhaps we should have left them and taken out our hardware. But the assumption seems to be: leave them the equipment, leave our people there because it's a stable Afghan gov't we put in place. The assumption was wrong, though.
Chinese maybe flabbergasted to see some of the INTEGRATED CIRCUITS (IC) used by US military may have been manufactured in China. Remember Boeing, Lockheed martin and Douglas have manufacturing plants in China. They use computer parts made in Communist China. Thanks Bill Clinton for making China as "Most favored" trading partner of the United States since 1994...
