Wow.... that's a bit of a surprise. he was 85, but still.....

He was a scary guy.... a power-hungry and power-grabbing SOB. Haig may best be remembered for his statement about being "in charge" (as dt pointed out) after Ronald Reagan was shot and VP Bush had not yet come back to Washington, DC. He was, in effect, usurping the US Constitution with that (incorrect) statement.

He was loved by the Nixon White House, and probably rose from a colonel to a 4-star general quicker than anyone else in the country's peacetime history because of that.
