I dimly remember it(as it was a long time ago)... Some fought the yellow man with rifles, some with guns, other with math, Sitting in the back of a 3/4 truck, 12 place log-log tables in hand, writing down the numbers, Log for Tan of 9,482.93 mils, added to the line above, and so on, All done by hand, not even a adding machine. The end result located the cannon, two guns and two howitzers, mostly, If they knew where they sat they knew where to shoot. Just a clog in a vast war-machine. I, on the other hand, mostly drove a 2 1/2 ton truck. Such is the importance of good math!
