If you haven't already read it,
@ugeauxgirl, I recommend a library copy of "You're On Your Own (but I'm here if you need me)."
In this case "here if you need me" is more emotional & cheerleading support than being physically present.
When you see a new recruit after graduation, they're... different. Mostly in a good way, but maybe not (by your parental standards) all good. Hopefully those differences don't lead to discord in your house, and that book has the following helpful analogy:
"Imagine that you’re hosting an exchange student at your house for a semester. They’re from a completely foreign culture in Africa or Asia. They wear strange clothes, have a nose ring and tattoos, and maintain an unusual hairstyle. They eat wildly different foods that you’d never considered keeping in the house, let alone eating. They speak English but use a different vocabulary. They share the same basic human values as you but have totally different opinions on music, fashion, life, work, entertainment, living standards, and relationships.
As a host, you’d love spending your time getting to know this person. They might be fascinating or mildly repellent, but you’d be interested in them. You’d like to share their world. You’d want to understand their culture, their background, and their lifestyle. The experience would be unforgettable, and you’d be eager to repeat it with another exchange student.
Now imagine that the exchange student was actually your 18-year-old. A paragraph ago you thought that this exchange student was “fascinating” and someone you wanted to get to know better. Now that they're actually your offspring, suddenly there’s a problem?"
The analogy is in the chapter titled “You Pierced
WHAT?!?”
While you're at the library, I recommend that you browse any of the "Sub Tales" or "Silent Service Remembers" books by Charles & Frank Hood:

Of course your son should read them too, but I suspect he'd want to wait until he finishes recruit training. I wish I'd read them before I joined the submarine force 40 years ago.
On the financial side, he's going to be auto-enrolled in the Roth Thrift Savings Plan (the federal govt analog of a 401(k)) at an automatic 5% of base pay, and the contributions will automatically go into a target-date fund. All of these auto-defaults are difficult to change (yet hypothetically changeable) and essentially impossible to deal with during recruit training.
There are lots of other financial options (like Roth IRAs), and the TSP's target-date funds have their own issues. Yet all of those defaults are good enough until he graduates from recruit training (or even Nuclear Power School) and has some spare time to think about his investing.
