"The 'Nightingale' or the Freedom Legion, Lutèce branch made its only and greatest mistake in this operation by underestimating the Empire's determination and combat power.
Whether it was the regular combat forces or the number and configuration of special squads, their predictions were mostly accurate. The only mistake lay in the configurations of the 'Siren' and the 'Legion'.
This was not accidental, not at all.
As old rivals who have competed for many years, both sides are well aware of each other's operational patterns and strengths and weaknesses. Just as the Freedom Legion understands how the Empire would react and retaliate in such a situation, the Empire is equally aware that the Freedom Legion strongly selects and trains psychic ability users, applying them extensively across various battlefields. Hence, the Empire's strategy for this operation was based on the premise that their own configuration and layout would be predictable.
