[Tagging] How to tag earth walls in a shooting ramge

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. Look at this example
