For anyone who is interested in knowing if she ever ended up shooting a fascist, here’s the relevant paragraph from Wikipedia:

As she was extremely nearsighted, Weil was a very poor shot. Her comrades tried to avoid taking her on missions, though she did sometimes insist. Her only direct participation in combat was to shoot with her rifle at a bomber during an air raid; in a second raid, she tried to operate the group’s heavy machine gun, but her comrades prevented her, as they thought it would be best for someone less clumsy and near-sighted to use the weapon. After being with the group for a few weeks, she burnt herself over a cooking fire.
