Camp

[Marcus Julius]

I remember seeing a carving on which soldiers were doing work such as mortaring a wall in armor. Whether or not this is the artist just wanting to make it obvious that it was soldiers doing the work, or if soldiers actually worked in the armor is of course modern speculation. My memory keeps leaning toward this being something of constructing Hadrian's wall.

If it is a truthful representation, it's also possible that policies would have changed once they had the relative safety of the wall after completion, too.
