「Foot motions with army meatwagon」「motions surrounding rotation of screwing with plugging orifice and then screwing again」describe the LUCK OF THE DRAW as to which 'comfort' woman was available for the next in line, one's date with DESTINY, whether a soldier fulfilled his fantasy or was stuck with a duroc, whether he missed getting a dose of the clap, or not, depending upon who was in the line before him and which woman was his LUCK to be assigned for the next three minutes.「Two no-longer-integrated feet in rotation with army soldiers」exemplified FATE and DESTINY both as soldiering, and as a comfort woman's lot in life.
　Nowhere in usage does this glyph exclusively refer to luck, fate, destiny or fortune as good…sometimes the only luck someone has is bad luck. An「army in motion」must certainly TRANSPORT a great amount of various materiel. And if LUCKY in battle, also needs to transport the booty back home (that is, if they win and are still alive). In any case, a soldier's FATE and DESTINY, and perhaps the fief's as well including whether all the inhabitants might become someone else's slaves, were decided each time the lord's「army moved.」This glyph refers to TRANSPORT of goods generally since the only mass movement of goods in a procession of vehicles back in the good ol' days was when someone's army happened to be passing by. Everyone else seldom ventured more than a few kilometers from home or the farm (why would they?), other than visiting a nearby town for some excitement.
　Military use of comfort women was not a Japanese invention, formerly…everyone did it: pirates, bandits, gangs, armies the world over…because they could. See this researcher's website blog and well-documented published material to learn about the relationship between Japan and Korea prior to WWII, who it was that actually recruited Korean women as army service providers (in nearly all cases), and who is behind why this issue remains a propaganda flashpoint today:
　「I first confronted the comfort women issue in 1991. It was near the end of my study in Japan. As a volunteer I was translating former Korean comfort women's testimonies for NHK. When I returned to South Korea, the nationalism was out of control. The anti-Japanese activist group 'Korean Council for the Women Drafted for Military Sexual Slavery' (also known as Chong Dae Hyup 정대협 挺対協) was formed by the South Korean communists. Its leader said publicly it was determined to defame Japan for the next 200 years. Its propaganda turned me off, so I stayed away from this issue for years. I regained my interest in this issue in the early 2000s when I heard that Chong Dae Hyup was confining surviving women in a nursing home called House of Nanumu. The only time these women were allowed to talk to outsiders was when Chong Dae Hyup needed them to testify for the UN Special Rapporteur or the U.S. politicians. But for some reason I was allowed to talk to them one day in 2003. I could sense that women were not happy being confined in this place. One of the women (Bae Chun-hee) told me she reminisced the romance she had with a Japanese soldier. She said she hated her father who sold her. She also told me that women there didn't appreciate being coached by Chong Dae Hyup to give false testimonies but had to obey Chong Dae Hyup's order. When Japan offered compensation through Asian Women's Fund in 1995, 61 former Korean comfort women defied Chong Dae Hyup's order and accepted compensation. Those 61 women were vilified as traitors. Their names and addresses were published in newspapers as prostitutes, and they had to live the rest of their lives in disgrace. So the rest of the women were terrified of Chong Dae Hyup and wouldn't dare to defy again. Chong Dae Hyup (some of its members were arrested as North Korean spies) has used the comfort women issue for its political purpose, which is to drive a wedge into U.S.-Japan-South Korea security partnership.」

　Or, do you believe the North Koreans?
