That interpretation sounds like a plausible socially progressive reading of the law, given that there’s a proviso to address cases where a person rapes a military spouse “by means of violence, coercion or other means” (it refers such cases to Article 236, which concerns cases of rape by violence or coercion in general). One could argue the addition of this proviso implies that the entire article is intended to be read as a law to protect the welfare of military spouses, addressing different ways a man could take advantage of a lonely military spouse, either by dishonest seduction (dishonest because conviction under the law requires proof of the man knowing that the woman is already married), or by force/abuse of position. The relevant clause of the Chinese criminal law code reads:

第二百五十九条　明知是现役军人的配偶而与之同居或者结婚的，处三年以下有期徒刑或者拘役。 利用职权、从属关系，以胁迫手段奸淫现役军人的妻子的，依照本法第二百三十六条的规定定罪处罚。

Article 259: Anyone who cohabits with or marries a spouse of an active-duty serviceman knowing that the spouse is the spouse of an active-duty serviceman shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention. Anyone who uses his power or subordinate relationship to coerce and rape the wife of an active serviceman shall be convicted and punished in accordance with the provisions of Article 236 of this Law.

Of course, the broad way that the law is phrased reveals big blindspot in the provision, as it kinda fails to consider or address a possibie situation where a military spouse could or would want to exercise agency by actively seeking out affairs while their spouse is deployed.

Edit: Actually, upon reading the criminal law code further I realise that it also contains a general criminalisation of bigamy in Article 258 (anyone “who has a spouse and commits bigamy, or who marries another person knowing that the other person has a spouse” can get up to two years imprisonment). So, I guess in cases where a military spouse actually remarries while the soldier is deployed, that would also open her (or him/them) up to some criminal liability. However, if she’s “merely” having an affair, or cohabiting, she’s technically not liable for any crime. Which means, on a structural level, the law is a little more lenient on the military spouse as compared to the jody. This further supports the argument that it’s more accurate to read Article 259, which addresses only the person seeking to marry or cohabit with the military spouse, as theoretically aimed at protecting military spouses from being taken advantage of while their husbands are deployed instead of it being a law meant to punish military spouse infidelity, since it distinctly doesn’t seek to punish the cheating military spouse like Article 258 does for general bigamy. If Article 259 was intended to punish all military spouse infidelity, it logically would need to treat both the military spouse and the person they cheated similarly.

You know this is a good loophole. I’m gonna tell you about the time an older student (at least in his mid 30s) argued with the professor for about 5 mins in class about what the author of the assigned reading actually meant to say. The professor, to his credit, tried his best to explain in plain English terms what the article meant but the student just wanted to argue. In the end the professor goes “Okay, look at the article. Now look at the author’s name. Okay, now look at your syllabus and look at my name.”

Student dude immediately said “sorry” and sat the fuck down. He had been arguing with the professor over the professor’s article all along.

I have to ask, is this an Anglo nation

This was an Anglo nation but it would surprise a lot of people to know that many Anglo nations don’t have a written constitution or bill of rights.
