War History Studies Department
From Gineipaedia, the Legend of Galactic Heroes wiki
The War History Studies Department was part of the curriculum that cadets of the Free Planets Alliance Officer Academy studied during their training. The War History was by no means a core department. Rather, it was a series of complimentary subjects that cadets could choose, allowing said cadets to graduate with a degree in history.
The existence of the department - and the fact that it was free upon signing up as an officer - was the reason Yang Wen-li became a soldier. Unlike most of his other classes, which he had little interest in, Yang was the top student in War History.
Unfortunately, budget cuts forced the Academy to close the department at the beginning of Yang's third year, despite a campaign to stop it started by Jessica Edwards.
