About Face

"About face" is a military command that instructs soldiers to turn 180 degrees, facing the opposite direction from their original position. It's a precise maneuver used in drills and formations to quickly change direction while maintaining discipline and coordination. The phrase has also entered everyday language, meaning to completely reverse one's opinion, attitude, or stance on a matter. This idiomatic use reflects the idea of turning fully around, symbolizing a significant change in perspective or strategy.
