found this bit of cool info on overcoats and the fact that it is not "reenactorism "
From Revised U.S. Army Regulations of 1861, Article XIII, 96.
The knapsack of each man
will be placed on the lower shelf of his bunk, at its foot, packed
with his effects, and ready to be slung; the great-coat on the same
shelf, rolled and strapped; the coat, folded inside out, and placed
under the knapsack; the cap on the second or upper shelf; and the
boots well cleaned.
