LOL. At least when I was in the Army 2002-2006, they were still teaching land navigation using map, compass, and protractor. GPS-enabled devices were absolutely forbidden on the land nav course. We also did night land nav, which was definitely more difficult :) I would bet the military still teaches folks how to navigate sans-GPS, because assuming GPS would remain available during a conflict with another great power would be... foolish.
Also, north-is-up mode is the only way to go when navigating with your smartphone :)
