What emblem did Arjuna had on his chariot flag at the battle of Kurukshetra?

Hanuman-arjuna had this emblem of hanuman. srila prabhupad writes in bg 1.20 purport the emblem of hanumn on the flag of arjuna is another sign of victory because hanumn cooperated with lord rma in the battle between rma and rvaa, and lord rma emerged victorious. now both rma and hanumn were present on the chariot of arjuna to help him. lord ka is rma himself, and wherever lord rma is, his eternal servitor hanumn and his eternal consort st, the goddess of fortune, are present. therefore, arjuna had no cause to fear any enemies whatsoever.
