Furlien was locked in his cabin, he had to hold out for two days until his plan could be executed. On the last day, even just minutes before the actual maneuvers began, the big move would be made.
The hidden men armed with non-simulated heavy weapons and Battle Suits would break into the hangars to subdue the cadets in charge, the rest of the underworld people, although unarmed, should have no problems subduing the rest of the civilians.
At first, his plan did not include the presence of civilians on the list of volunteers, they were all supporters of the reactionaries or members of the underworld, but the flaw in this idea was the presence of the cadets. Killing them was an option, but as soon as there was a transmission of orders from the academy management at Harpe, the action would be discovered and something strange was happening.
