From Destinypedia, the Destiny wiki
War Beasts are feral, vicious attack animals deployed by the Red Legion as either shock troops, a distraction or as cannon fodder to protect their other forces. These beasts are quick and highly aggressive and will attack any enemy in sight. They are also very tenacious and will not stop until either they or their enemies are dead.
War Beasts have no ranged attack abilities but compensate for this with their incredible agility and unyielding ferocity. While they are weak individually, and can be downed in just a few shots, they make up for this by being deployed in large numbers which can easily overwhelm enemies. Once they get in close to their enemies, they will relentlessly strike at them with their claws, teeth and blades affixed to their backs.
