Which of the following is NOT one of the five types of minefields?

The five types of minefields are categorized based on their intended purpose and placement in military operations. The correct answer is "Supportive," as it is not recognized as a standard type of minefield.

Defensive minefields are employed primarily to protect an area by impeding enemy movement and providing the defenders with a tactical advantage. They are strategically placed to thwart enemy advances and are often used in combination with other defensive measures.

Phony minefields are deceptive in nature; they are constructed to mislead the enemy into believing there are actual mines present when there are none. This psychological tactic aims to cause hesitation or misdirection among enemy forces.

Barrier minefields are designed to channel or restrict the movement of adversary units, often used to funnel them into areas where they can be engaged more effectively by friendly forces.

The reference to "Supportive" minefields is not found in standard military doctrine or classifications, making it the correct identification of an option that does not belong to the list of recognized types of minefields.
