Something I've been wondering, why is ribeyrolles often depicted with a blood bag?
The game wiki says:
There is a theory behind the Intravenous Drip Chamber placed on her:
The pyrrhic victory of French forces in World War I was considered to be a first theory of Ribeyrolles, as the French forces suffered 1.300.000 casualties and 4.200.000 wounded during World War I. The uniform she wore resembles the French forces in the Franco-Prussian War in which the French suffer a loss and 750.000 casualties from Prussia.
