Are the animals just animals or do you get to wield them via a pet window or something? Pretty sure 50 hawks can fuck the hunter up and bring you his gun.
Pending good answers then it's Rats and Hunter. That gives you 100 rats to throw at every enemy, and the hunter to take out the Hawks, then work down anything remaining. Easy Peasy.
