June 7, 2011: U.S. Marine Corps artillerymen have developed a solution to a growing problem; compasses confused by the growing amount of metal (like tanks and other vehicles) found in the vicinity of the compasses used to calculate where to point the guns. Some marines realized that they could do away with the compasses by using a mathematical technique called trilateration. If you can measure the distance between two known points, you can accurately (enough for artillery fire) determine the coordinates of an unknown location (the target). The new USMC method, when tested, produced more accurate target coordinates than older methods using a compass (that was not being messed with by large, nearby chunks of metal). GPS, laser rangefinders and more accurate maps make precise trilateration possible.

Artillerymen have long been known as the geekiest of combat troops.
