Even as a noncombatant, the military is a sea of immorality, sex, even drugs, and women in the service are implicitly encouraged to be (and often are) whorish.
You should not seek a wife there unless you find quite the exception.
The military is not interested in your desire to access *Catholic* sacraments or clergy. You will, at least, have access to a 'chaplain' who may or may not be a Catholic, and they need not even provide you with Catholic 'Mass', and will tell you your spiritual needs are accommodated by the offering of a non-denominational "Christian" service.
This may or many not happen, but be aware it is a possibility. This particularly complicated confessions as well.
Lastly, you will have to endure immoral men in your unit, who will be the norm, as well as an insistence you tolerate now-open homosexuality.
These things would be true of almost any job, although the military magnifies these issues of immoral, unCatholic coworkers by also controlling where you live and in what situation you live (until you decide to get your own apartment off base).
So, it can be endured. You'll have to endure the world eventually anyway, but the military is different from being a waiter at a Chili's while you work your way through a community college, because you can go *home* at the end of the day instead of rooming with degenerates (possibly, although there are good people who are not Godless in the military). You can attend Mass on Sunday if you work at a restuarant, retail store, fast food, etc. The military you may get deployed and have to rely on the Mass options (or lack thereof possibly) available where they deploy you.
So, it has pluses and minuses. You will certainly make more money in the military from a lifestyle perspective than you will working entry level jobs while you go to a junior college.
Another option is a skilled trade apprenticeship. People say these require connections, and while knowing someone in a trade union helps, you can get an apprenticeship through diligence, especially since most entrants into apprenticeships "washout", that is, they do not finish because they are unmotivated or uninterested.
You can literally call unions and/or go to their websites to inquire about apprenticeships, or ask a local licensed tradesman (depending on the state you live in) if they'll take an apprentice or know someone who is.
There are more than plumbing, electrician and carpenter.
There are millwright, elevator mechanic (the highest paid bar none), structural steel, various portworkers like the longshoreman, boilermakers, etc all of which have unions and training programs.
Good luck, and pray for St. Joseph's intercession. Set yourself up to be able to afford a family by getting a skill.
