Not Really. The US military has never been known for precision navigation, that's why GPS was invented!

I prefer this Compass;

Baseplate compasses are designed for speed and ease of use with grid co-ordinate map navigation, so the new Cammenga compass is not exactly an orienteering compass.

This Cammenga baseplate compass is a essentially a military compass hence the preference of the use of Mils rather than the poorer +-5 degrees scale. Even the Cammenga M-1950 sighting compass won't be any more accurate in use for navigation than the Recta DS-50G with its adjustable declination correction scale. i.e. it will improve accuracy and speed of navigation as you don't have to mentally add/subtract the magnetic declination angle to the measured azimuth/bearing assuming that the M-1950 users know of such things!

The Cammenga M-1950 will be tougher and can be used in tougher environments, but you probably wouldn't want to walking around in such weather though.
