I can sympathize. In the Army, the first time I went for my Expert Infantry badge, I failed on the depth test. There's a section set up to call for artillery fire, and you have to judge random distances by eye, some of which can be hundreds of meters. It's much harder than it sounds, and it's amazing how many people fail this portion of the course. 75 meters looks an awful lot like 125 meters with no obvious visual markers, and it gets exponentially worse with increasing distance

BTW: I eventually got it
