A thorough training should begin with little technology and then make things ever easier with technology as performance expectations rise during training.

An example: GPS
A map and a suitable compass should suffice, and soldiers should know the polar star (or whatever the people on the southern hemisphere use).
GPS-dependent soldiers are often an embarrassment when they're being tasked to navigate without GPS.


I'm also in favour of having plenty motorcycles in an army for traffic control, courier and rear scouting (such as finding a good spot for a depot or hospital).
