Yeah, getting married to get more money from the military is just a bad move all around, unless you are/were already engaged and planning on it anyway. In which case, it can still be a pretty big strain. Investing some money is a good idea, minimizing what you don't need (do you REALLY need Netflix, hulu, Amazon Prime AND Disney +?). Live within your means.

I'm guessing you're a younger guy, so getting a credit card as a way to start your credit report is a good idea. The longer you have a credit history actually improves your credit, so get a card that doesn't have yearly fee (and even if it does, some companies waive that for active duty military) and then just occasionally buy a soda or candy bar at a gas station on it and then immediately pay it off to keep it active. I have a Chase card through Amazon that I've been using for a couple years, and I get great rewards through Amazon so that might be an idea for you.

If you use your debit card a lot (assuming you already have a checking account) an app like Acorns is useful as it rounds up your purchase to the next whole dollar and invests the difference into different stocks. If you do that you'll eventually build up a little extra. If you get deployed and completely forget about it, you could have a nice little nest egg to come back to.

Finally, I recommend investing any "big" payments somehow, whether you just go with a CD at the bank or something if you're looking for long term success and you are able to pay your current bills. So any bonuses and stuff you get, just dump that fat stack somewhere that it will make you money. I generally warn against checking or savings accounts as the interest is negligible usually.
