The US military has never been known for precision navigation, that's why GPS was invented!
I take issue with that comment! Of all of the foreign military units I have worked with (including the best of the UK), there are few who teach land navigation the way the US military did. I have been retired for a while so I do not know how much of the training is done now, but special operations units still teach map and compass before using a GPS. In my experience, only the top special operations units were teaching that type of navigation at the lowest levels. Except the armed forces of Canada, New Zealand and Australia who all used to teach map and compass very rigorously down the the lowest squaddie.
I am just poking at you, I too know that most military units do not teach it extensively or well, in my opinion.
I do agree with the comment about not being able to use it on the map very well. It looks like they are trying to do too many things with it, and none of them very well. I generally carried a Silva Ranger while I was in the Army. The lensatic is bulky, heavier and slow. It is however durable and the mils are important, or at least used to be, when calling for fire. I don't know why they would include that on this compass. Maybe they had too many of those old parts left and are trying not to lose money.
