- Using pickup trucks with shooters concealed in the bed of the trucks;
- using motorcycles as a shooting platform for drive-bys and assassinations;
- executions of prisoners;
- ambushes of law-enforcement officers;
- residential assassinations;
- assassination on a golf course using a rocket-propelled grenade and rifle fire;
- drive-up kidnapping of target walking on a street;
- use of tunnels, storm drains and sewers for infiltration during urban raids;
- rappelling from rooftops of buildings to make entry on upper floors;
- use of motorcycles for grenade attacks; and
- raids on buildings with large numbers of occupants - perhaps schools or office buildings.
No hostages will be released. Their ritual executions will be recorded on video tape. (Sounds like the Pearl execution to me.)
Another scenario they mention is getting a home owner to open their door and then emptying their pistol into them.
Not exactly 'World Trade Center' operations, but they're all in the al Qaida playbook.
