TOWING OPERATIONS ON GRADES (CON'T.)
Expedient Method
Measure the distance between the road and the bottom of the
wood. If it is 3 inches, you are on a 30 percent slope; 2.5 inches,
and you are on a 25 percent slope, and so on.
Eye Sight and Pace Method
One other way of determining grade is the eye sight and pace
method. You need to know your height and the length of your stride.
If a soldier is 6 feet tall and his step is 2 feet long, he stands at the
bottom of the hill and picks a spot on the hill that is the same height
as his head. He then walks to that spot counting his steps. Once he
reaches the spot, he multiplies his steps by his stride (2 feet) and
then divides his height (6 feet) by that number, multiply by 100 and
add 1.
