man-made=embankment on a way (line) is defined as the top of a *one-sided* slope. man_mde=embankment on a highway is not defined in the wiki, but it is in use to indicate that the highway is on top of a one-sided slope. My suspicion is that it is occasionally also used for the situation where the way has embankments on both sides, a situation which should be tagged with highway=* and embankment=yes.
man-made=embankment is used on closed ways, without area=yes, to indicate an extended structure, but one has to be careful, this defined the flat area on top of the earth structure, not the footprint of it. In the case of the small-footprint earth walls of the shooting range, this difference can be neglected. But, changing subject to the large dyke structures which you may find along big rivers, the dfference between footprint (base) and the top edge can be enormous.
