I don't know for sure. It could be either. There are real - life cases of privacy invasions in locker rooms, but it could also be a fictional plot created for a book, movie or just a made - up story to teach a lesson about privacy.
I'm not entirely sure as there could be many novels with the term 'war room' in the title. It might be about military strategies and operations that are planned in a war room setting.
A 'war room story' might also be in a business context. For example, in a high - stakes business deal, the war room could be where the top executives gather to plan their marketing strategies, deal with competitors' moves and figure out how to gain an edge in the market. They analyze data, discuss different scenarios and make crucial decisions to win in the business 'battle'.
