In a Mail Call video, R. Lee Ermey answers an e-mail from Marty in Orlando asking what a daisy cutter is. Ermey explains that a daisy cutter is a civilian term for the worlds largest conventional bomb, known as the BLU 82 or Big Blue 82. This bomb was first used in Vietnam to clear landing zones for helicopters and is the size of a small car. Big Blue 82 is still in use today and remains virtually unchanged.
