Yeah, I knew a few like that. Free education while servicing the officers on duty weekends.
The Red Army of World War 2 had female clerical staff at the division level and higher. In addition to the clerical staff duties, they were pretty much there as “war wives” for the officers. Some got married to their “war husbands” in May 1945. Other officers just went back to their “peacetime wives.”
Do we really expect anything different? People will do what people do.
