So how did the Taliban get trained (pause)?
In 1976ish there was a coup or coup attempt. This led to a bunch of different uprising in one. A military coup won out and the ended up becoming more fundamentalist. The army and Air Force enforced the laws. Russia invaded in 1977ish in response and dominated the Afghans real quickly. It was a combination of Russians and other Soviet republic countries. They hired Afghans as guides, used some of them as additional fighters, interpreters, etc. they trained them to be Russian soldiers since the Russians considered them part of the Soviet Union. The Afghan army and Air Force disbanded and began a guerilla campaign. They were already trained but needed more arms and funding to make it work.
Eager for an opportunity to uno-reverse the communists for Korea and Vietnam. The US began dropping Anti air weapons and CIA liaisons. The CIA gave intelligence, money, weapons, and training for anti air weapons to combat the Russian air bombardments.
The Afghans already knew how to fight a guerilla war and, though they died a lot during the conflict, they passed the lessons on.
After the USSR gave up the educated Afghans, that experienced the modern Kabul in the early 70’s were killed and scattered in the fighting. Many left the country to the grandparents and parents of those we see today. The Taliban that grew out of the mujahideen (that fought the Russians) continued to pass on combat experience and used them to further cripple the rest of the country.
The found that there was infinite money to be made by turning the country into a giant trap house, selling opium, women/girl sex slaves, illegal arms/munitions etc. all this under the guise of fundamentalist Islam. In truth it was all for the money. The old mujahideen that didn’t want to participate became warlords, shadow governors, mercenaries, farmers.
After a whole the Taliban fukked up and started using Afghanistan as a pay-for-play terrorist training resort. 9/11 happened they got invaded and ran off the block into Pakistan. They gathered their forces and returned every spring. They returned in the winter to lick their wounds because they got donkey fukked every time. A lot of the older ones died off, retired, became shadow governors, politicians, etc.
They continued to train, learn, and refine themselves. They continued to get donkey fukked until we left and they could come out and let their nuts hang like Smokey when deebo goes home.
Long story short they already had their training. They learned a little from us but, like any capable force, combat skills are gained through experience and repetition. Theses are the professional descendants of the old Afghan Army and Air Force. The Taliban actually had an Air Force for a little bit, back in the day, if you want to look them up.
