Ans. The Vanarasena was of great help to Rama in Lanka Vijay. Without them, defeating Ravana would have been difficult for Lord Rama. Hanuman, who was an important part of Sugriv's army, agreed to go to Lanka in search of Sita. Nal and Neel, with the help of their monkey army, built a bridge to reach Lanka. Bali's son Angad gathered all the monkey's to help Lord Rama win the battle. During the battle, Vanarsena fought bravely many died and many were severely injured. They didn't lose hope, and because of them, Rama was able to defeat Ravana and bring Sita back safely.
