I still remember the days when each artillery battery had its own Mess Section, and on a 4 day field training exercise, the mess section started making coffee the first day and just kept adding more coffee grounds and more water as the days passed. 2am on day 4, i'd nudge Chief of Smoke and say..."Let's head up to the Mess Truck and cut us a hunk of coffee" That stuff would pin your eyes open for you.
