Since introduced in the early 1990s GPS (satellite based navigation) has revolutionized movement in unfamiliar areas and nowhere was this more apparent than in the military, where so many personnel on the ground, flying aircraft and steering ships operate in unfamiliar surroundings. Yet after a decade old forms of navigation (using compass, sextant and maps) began to fade away in the military. But after a few years a growing number of commanders, and their subordinates, realized that that satellites could fail or be jammed and the only alternative would be to fall back on the old ways. Training was revised.Training was revised? Really? GPS is a tool, but it's not the end-all in land navigation. And, lete me tell you a little secret; when you're riding in 50 tons of steel, a compass isn't any help either. Navigation from a steel container is by terrain association, keeping track of the sun in the sky, or the way a creek is flowing, or where that big terrain feature might be. A compass is certainly useful, A GPS is certainly useful, but it's not a crutch.
Which reminds me. I need to buy a new Rand McNally atlas and put one in the new vehicle.
