Fisk

"No sooner had I put the Grunt down than Fisk has got a hold of that bad boy and dumps the whole clip into the column—stickies and everything just cooking off—secondaries like mad! Fisk was a crazy bastard he was—wish he was still with us."

Fisk was a UNSC Marine who fought during the Second Battle of Earth. Not much is known about him except that he used a captured Fuel Rod Cannon to great effect in a firefight with Covenant forces and that he may have died at some point after that.
