During WWII prostitutes who followed the troops around, sometimes wore army boots or combat boots. It's akin to calling some one's mother a prostitute.

your mom has to work, somewhat specific to army work or working in the army, it is an old saying that probably existed when women were not allowed to do much of anything except sleep with thier husbands and clean thier kitchens in the nude.
