The Exercise

An attack on a large mall has two teams go down both sides of the mall shooting and tossing grenades. Several calls from JCPenney’s to 911 are some what helpful. They get away with some cleaver tricks.
Then the exercise is called off and the FBI evaluation teams go through the mockup mall. After they are complete, they will be reassigned. But they are driven by HLS to Fort Lewis south of Seattle for a special project. The 3-teams are told to plan an attack on the airport, ferry system, and the Seattle bus tunnel. The plans go back to DC and are tabled as not necessary.
The reconstruction team misses a transfer, and both go to Portland to handle security alerts. The two-person planning team makes the transfer cut off.
One of the security alerts in Portland is the missing of 20 rifles from the army. They were found by accident going to Portland for shipment. A similar batch being shipped out is found to be short several cases of dangerous ordnance for harden targets. Everyone is nervous, and the two planning agents are air shipped to Portland that were on one of the original three teams used by HLS.
The 4 agents are moved to a safe house which is blown apart right after they sneak out. They take all the safe house’s money and hide. The 4-FBI agents have no idea who they can trust, FBI, CIA, HLS, NSA, or the army.
They risk trusting the army in Portland because they reported the missing rifles. They determine the target is the Seattle bus tunnel. The very same one they planned the attack on.
The FBI teams knows their plan but how much has been changed?
They did not plan on the leader of the raid escaping or they type of explosives that would be used. The army has soldiers as civilians on buses and at every station in the tunnels, waiting for an attack. The attackers appear to be following their plan of putting their armed people in the tunnel.
When it starts Metro tunnel security is removed in moments and large trucks are easily placed in the south entrance to the tunnels.
The army will have a vicious battle to stop the well-planned attack.
