The Times of London talks about the large roster of foreign fighters in Pakistan's tribal belt. They serve as shock troops that consolidate al-Qaeda's local control over the tribes in Pakistan, and also conduct operations in Afghanistan.
"First-hand accounts from locals in the lawless areas of Pakistan close to the Afghan border, combined with those of Pakistani officers in the region, suggest that there is no shortage of Islamic foreigners willing to join the fray. Britain claims that these fighters are still the source of 75 per cent of terror plots against it.
Among this disparate group are al-Qaeda's Arab fighters, with a reputation for being well heeled and well mannered; Uzbeks from the Islamic Movement of Uzbekistan (IMU), regarded as tough, rough and poor; and the Punjabis of Lashkar-e-Taiba (LeT), viewed by their hosts as arrogant but militarily competent."
That said, Islamic paradise has its drawbacks. If we're clever enough to exploit them. Right now, we're doing the exact reverse:
"It's because of them that the army has come to our land and destroyed our homes," one local tribesman said. "Because of them our businesses are wrecked. Because of them we live as internal refugees.
"I've met ordinary people who say that they'd even welcome Israel or India if they helped us get rid of these Arabs and their friends."








Long War Journal referred to these guys as AQ's Shadow Army , which evolved from the pre-9/11 055 Brigade.
