"The Master Chief was a man of few words, and his vocabulary had no room for niceties. His job was to accomplish his mission in the most effective manner possible, whatever that may be. As such, he came off as blunt, cold, and stoic, which was entirely the point.
This quote sums up the Chief rather accurately. He wasn't one to wait for someone to offer up a solution, but rather someone who took charge and did whatever was necessary to finish the job. This ended up saving Earth on multiple occasions."
