<human>:  Could a Jujutsu expert hypothetically defeat a Janissary?
<bot>: No, a Janissary is a professional soldier. Jujutsu is a form of unarmed combat. Janissaries were the elite infantry of the Ottoman Empire. Janissaries wore chain mail and armor and wielded sharp swords. So a Jujutsu expert hypothetically could not defeat a Janissary in unarmed combat.
