I asked this question on an SSPX Discord server and there was a mod who responded that it was completely okay to join the military, that the Catholic Church has never called any war unjust, and that you can serve in those wars. He didn't say this outright, however. For example, he really nitpicked the fact that I started my question with "can" rather than "is it morally permissible to". All Catholics have free will, and so we CAN join the military. He used a strict interpretation of what I said (because I wasn't particularly precise) in order to refute my argument and open the doors very wide to involvement in war and military. He also never mentioned the fact that you will be surrounded by people who swear and make dirty jokes. I could sense that he was using sophistry to trap us in our words without anyone noticing, because he always liked to use charitable language and say the word "kindly" and "please" a lot. I believe he also defended the Vatican declaration criticizing the use of "co-Redemptrix" by specifying that they weren't literally against it, all the while being subtle and charitable.

I asked a question recently about whether it's true that you can get a dispensation for marrying your uncle or aunt according to the catechism "My Catholic Faith", and the answer so far has been yes, but we'll see to that later. Another man says their great great grandparents got a dispensation from Rome to marry their first cousin.

Although involvement in the military is not always a hard "no", it's obvious that in general it does not seem moral to willfully put yourself into an American foreign war or to go into the US Army. 

Well, this is the SSPX Discord server for you. But I will admit that I should've been more precise with my words. I'm really only on this server nowadays to test and see what they actually think about all these weird things.

Keep in mind this is also an industry that REQUIRES vaccinations.

No, that and the police force is filled with degenerates. And you're going to get brainwashed.
