I just finished doing the Return To Sender quest again, and man, Chief Hanlon still stands to be one of my favorite characters in Fallout. His story and personality just shows how much of a broken man he has become. How the war with Caesar's Legion totally broken him as man. His reasoning of doing what he did is really saddening. What are your thoughts on him?

He is a man torn between his duty and his fear for what to come. Hanlon is one of the reasons I can never truly trust the NCR in my playthroughs. Not because of him personally but because I see what the war has done to him, and understand what he fears.
Truly a wonderful character that makes us question our aligiance

Hanlon is one of the most interesting characters, it really shows the other side of the war. While most of the soldiers are "happily" serving their faction some have seen some bad things.

Chief Hanlon is a very interesting character. His actions in the game are dictated by his past and the fact that despite the heroic victory in the First Battle of Hoover dam had no illusions that the legion Caesar returns with an even larger force and NCR could not take advantage of the fruits of victory.
