McCasky

Template:Ratings Template:Human Character Infobox Second Lieutenant McCasky was a commanding officer groundside during the Battle of Sigma Octanus IV on a scouting mission with his squad. McCasky had underestimated the danger of the mission, assuming it was a "milk run", when he and most of his Marines were killed by the Fuel Rod Gun of a Hunter.

Four members of his unit did survive though, Corporal Harland, Private Fincher, Private Walker, and Private Cochran, which they escaped in a Warthog.
