The 'Tally' and 'Afgan' are army slang from Taliban and Afghanistan. The British Army official withdrawal from Afghanistan was 2014.
Here's the short version of the Taliban.
The Taliban came about after the Russian withdrawal from the country. Afghanistan was divided in areas that were controlled by rival warlords who were formally mujahideen fighting against the USSR. These warlords fought among each other and there was no sense of a formal Afghan national identity.
There have been so many wars there the place is packed with guns. Some of these are old SMLE, 303, rifles dated back to WWII. The Afghan's are also great gunsmiths and made many copies of guns. If you can imagine the old wild west, that's Afghan.
Afghanistan is connected by a network of roads. Everything, has to be trucked across the country from one end to the other. When trucks drove though the warlord's area they were forced to pay protection money to them to pass safety. The rates of this protection money went through the roof to the point it was crippling haulers.
The roads were also a very dangerous places infestated by groups of armed men who hijacked frate and killed drivers.
The truckers were loosely banded together in what we would call unions. The first, Tally came forward in Southern Afghan to offer security to these truckers as they travelled and it was the trucker uniond who banded together to pay them.
These were seen to be religious men and many were formerly mujahideen. They won the support of the truckers and the Afghan people in the 90s. At the start you could even say they were the good guys and although were devoutly Muslim were not the extreme nut jobs that the Tally grew into.
A element of even stricter religious leaders emerged at the top of the Tally. By this stage they grew too powerful. They eventually too key areas and cities. I can't remember the name of the place, but they slaughterd the people there when they took it. When the Tally took these areas, they imposed their strict form of religion and laws on the people. These Tally got more and more powerful and nobody could do anything to stop them.
I know that they impose the wearing of beards. Men without them were punished. Women must be covered, because only their husbands are allowed to see them. They believe a woman's beauty is in her eyes. A woman isn't permitted to go out alone. She is the property of her father and then the property of her husband. When a husband wants sex his wife isn't allowed to say no. Females are not allowed to lean to read or go to school,work or drive a car. Soldiers were not permitted to talk to a woman on the street, or stop and search her.
People were beheaded and hands cut off for very little. I heard a story once, a young lad who was caught stealing and as an act of mercy the bastards drove a truck over his hand instead of cutting it off. Woman are stoned to death for very little as well.
You may have realised that I don't really like the Taliban. I can't say half of how I feel about these bastards on here. God help ordinary Afghans who just want to live in peace and God help anyone who helped the ISAF forces when they were stationed in Afghan. It is against their laws for a Muslim to convert to be a Christian. I knew one Muslim family who had turned to be Christian and they risk being put to death if they are ever found out.
I'm no expert, I just know a wee bit about them from work, but I'm sure there are a load of stuff on the internet about the Taliban.
