Game
The recruitment officer looks at you funny. "I'm sorry," he begins, "we don't offer positions in the trenchlines for young ladies such as yourself. But if you're really keen on going to war, we do have some positions driving vehicles and other support work..."
As you have no other alternative, you accept. One day, you meet a strapping young soldier on the field, and you fall in love, get married, and have lots of children after the war.
