Concealed Obstacles
Concealed obstacles are used with the intention of not only preventing movement of enemy troops, but also causing casualties during attempted movement. Although one of the oldest forms of obstacle use, this became far deadlier with the invention of the mine warfare, and more so with air-delivered scattered submunition minelets that can create an instant minefield.

Famous quotes containing the words concealed and/or obstacles:
“Art can never match the luxury and superfluity of Nature. In the former all is seen; it cannot afford concealed wealth, and is niggardly in comparison; but Nature, even when she is scant and thin outwardly, satisfies us still by the assurance of a certain generosity at the roots.”
—Henry David Thoreau (1817–1862)
“It still holds true that man is most uniquely human when he turns obstacles into opportunities.”
—Eric Hoffer (1902–1983)
