How do you defeat raam on gears of war

You need four frag grenades a sniper with full ammo and a tourqe bow. Shoot RAAM when he is shielded and when the kryll leave him shoot him with the bow. Be sure to shoot him with the bow when the kryll are going back to him. It does him damage and scatters the kryll. When there are swarms of kryll in the sky stay behind cover that has lights on the floor.( It keeps them away from you). And when RAAM is unprotected, use frags as well. And if Dom is on the floor bleeding and he is near RAAM, DO NOT GO OUT FOR DOM!!!! He will not die. Just keep fighting RAAM. its crazy but you can also run before the lights go out at the end there is a machine gun u can die easy but it works
