"Pop Smoke" is a military slang term used to describe the act of quickly leaving an area or situation, often in a hurry or under duress. The phrase is used to describe the action of rapidly withdrawing from a location, usually to evacuate or retreat from an enemy. The term "Pop Smoke" is thought to have originated from the use of smoke grenades as a signal for troops to withdraw from an area, with the act of pulling the pin on the smoke grenade being called "popping smoke." In modern usage, the term is often used more broadly to describe any sudden and rapid exit from a location, regardless of the cause. The phrase is used to convey a sense of urgency and the need to act quickly and is often used in training scenarios to prepare soldiers for quick and effective responses to threats.
