We had khakis, we had trops, but we never had O.D.
Doggies wear O.D. We wear forest green and always have.
And we wore khakis when the word came up to "fall out in khakis."
Khakis were sort of a work uniform for office pogues. We had to wear them on guard duty and for inspections.
Trops were for liberty only.
You'd press those khakis until you could shave with the creases, fall out for inspection and 10 minutes later they looked like sh*t.
Impossible to keep squared away.
Our greens were wool, not the current fabric (it was for officers only back then).
You could get a decent crease in them by ironing them daily for about four years.
