I don’t know about that. You may know this already, but the Afghans Mujahideen did not use IEDs, especially of likes Iran is providing. This type of warfare was really perfected by Hizbollah in Lebanon and used by the Chechens more recently. I do think the Afghan Mujahideens could learn from the Iranians, for example, how to operate sophisticated Chinese made SAMs of the MANPAD type.
IED warfare is not rocket science....And there are plenty within the Mujahideen/ Taliban / Uzbek / Chechens that know more then enough for such type of warfare - Reality is Stan doesn't lend itself to such warfare as well as urban areas like Iraq - (but it is still a concern....just not on the same level at all).
As for MANPADs, again the Taliban / Chechens don't need any training whatsoever from Iranians....They'd teach them a thing or two in all reality.
No, the notion of Iranians teaching the Mujahideen or Taliban about fighting in Stan....is just foolishness. It is not needed.
But as I said earlier...They will always use weaponry...
