Answer: Narayani Sena (army)
Before the war, Duryodhana and Arjuna came to Krishna to ask for help. Duryodhana came first, but saw that Krishna was asleep. He sat down on a couch near Krishna's head. Arjuna arrived and, seeing Krishna asleep, remained standing at Krishna's feet. When Krishna awoke he saw Arjuna first and greeted him. Then Duryodhana said that he had come before Arjuna and said that he wanted Krishna's help in the war. But Krishna said that he had seen Arjuna first and thus Arjuna had the right to ask first. Arjuna asked for Krishna himself to aid him in the war and that left the huge Narayani Sena for Duryodhana, who accepted it gladly.
