Compass.

This is coolbert:

"On the ground troops are being reintroduced to the compass, paper maps and orienteering. Most managed to figure out how it worked before GPS when the joke was that the most dangerous man on the battlefield was a second lieutenant with a map"

Within the military dimension, the best ways are the old ways? Think in context map reading and land navigation.

Thanks to the Strategy Page Internet web site article:

"Electronic Weapons: Slide Rules And Sextants Survive In The Sky"

"December 6, 2021: In late 2021, Russian video appeared that showed a heavy bomber in flight with one of the crew using s slide rule, apparently to calculate course and/or fuel consumption rate. Most pilot training, especially for the crews of long-range aircraft, includes instruction on how to use special slide rules for such calculations in the event of problems with the electronic navigation and flight management instruments that do this automatically."

Training in navigation by the traditional methods used by the military not confined to the Air Force. Also done by the USN and USA. Marines too I assume.

IF AND WHEN GREAT POWER CONFLICT OCCURS, SATELLITES OF THE GPS VARIETY GOING TO BE A PRIMARY TARGET FOR THE ADVERSARY. A FALL-BACK WILL BE A NECESSITY. BREAK OUT THE LENSATIC COMPASS. ORIENTEERING AND FOLLOWING A COURSE ON THE GROUD FROM A MAP ABSOLUTE MUST!

Those of you who attended Non-Commissioned Officers school while on duty with the U.S. Army will well remember the SINGLE ONE REASON for failure and wash-out the inability to use a map, compass, determine your grid coordinates, etc.

Indeed! The American military for some time has done real-world training, operating in an environment where GPS no longer exists. See previous blog entries as relevant:
