How many tanks were lost in Afghanistan?
They weren’t lost. They were discarded.
Hmm, altogether or in the first 3 months?
The Times of London reports that the US simply abandoned a truly astounding arsenal of military equipment and weapons in Afghanistan. This reportedly includes up to 22,174 Humvee vehicles, nearly 1,000 armored vehicles, 64,363 machine guns, and 42,000 pick-up trucks and SUVs. So, too, the list of allegedly abandoned weaponry includes up to 358,530 assault rifles, 126,295 pistols, and nearly 200 artillery units. Oh, and the Taliban will likely inherit state-of-the-art military helicopters, warplanes, and other aircraft from the US, too.
None.. they were given away.
