Abstract: A door breach device can include: an elongate shaft having a first end and an opposite second end; a pivot mechanism at the first end of the shaft; a spearhead rotatably coupled with the pivot mechanism and having a tip on a tip-side of the pivot mechanism and having a shaft cavity on a shaft-side, where the shaft cavity is adapted to receive the shaft therein; a restraint slidably received on the shaft-side of the spearhead and on the shaft; a handle protruding from the shaft; and a hitch at the second end of the shaft. A method of breaching a door can include: forcing the spearhead through a door until the restraint releases the spearhead and the spearhead rotates by the pivot mechanism so as to form an angle with the shaft; and pulling the spearhead against the door until the door is breached.
