While you might find buttons and other relatively small things, the
chances are slim that a circa 1947 bivouac area would contain much of
anything else. The modern military is pretty good about "police", that
is cleaning up before, during, and after occupations. Police details are
especially common in long term bivouac scenarios. "A busy soldier is a
happy soldier" or at least one less likely to get into trouble. And make
work is part of that. This is a group that rakes sand into straight
lines and makes a fetish of picking up cigarette butts. And the
collected detritus is then usually trucked off site to an approved dump.
Spent cartridges are especially unlikely because troops were/are seldom
issued ammunition except on weapons ranges right before firing. If
anything were found it would be things like tent platforms, post molds
for tent stakes or poles. And given that most military tents use poles
that sit on the surface, even that would be tough.
