'New kind of militant' behind Pakistan Karachi attack"
"Military formation: One injured sailor told an official that the attackers "moved and dressed like us". The militants moved in tactical military formation and spoke in military parlance. They spoke between themselves in Urdu, as well as a foreign language.
Clothing and equipment: The militants wore combat fatigues, according to officials - and had night vision goggles, carrying rocket propelled grenades [RPGs]. "It takes months of training for ease with the goggles, and years to be expert," one official told me.
Tactics and a plan: One witness said that even though the militants had clear sight of them, "they ignored us... Instead, they just aimed RPGs at the two Orions [planes] parked on the tarmac." They were clearly under instructions to destroy military hardware. They also changed tactics easily and broke away in groups, which clearly had different aims.
Crack shots: "They were excellent shots - as good as any we have," said one security official involved in the operation. They used their night vision goggles to maximum effect, witnesses say - and that was an advantage they had until the SSG-N team arrived at the scene. When the gun battle began, one security official said, it was clear that these men could "hold their own" in a firefight. The fact that they had
M16 carbines and sniper rifles also set them apart."
