Ditch the sword, it won't help on Legendary. Grab dual Brute Plasma Rifles, or a Carbine. Take the grav lift up to the upper level and move around the hole until you can see him. Then wait for the Sarge to take his shield down with the Beam Rifle, once it's down, unload on him. Repeat until he dies.
