My very, very last MOS in the National Guard was 57E40 -- Bath and Laundry Platoon Sergeant (and Platoon Leader -- we were short officers). So for about 18 months I worked with washing machines and dryers. BIG ones, expensive ones, mounted on trailers. I had 40 guys who'd been to laundry school (nope, not me!).

Yeah, I know something about washing machines...and dryers, too. One thing I know is that you don't paint the microswitches or the dryer doesn't work and you have to wring out wool blankets by hand after the Adjutant General comes comes snooping around.

(There was also a Graves Registration Section attached to the Platoon. THEY spent their two weeks of summer camp in a tent, pretty much left alone, with a lovely area they'd measured and mowed and used as a practice area for golf shots.)
