WElcome Aboard, AFMark. Nice to have you here.
I see you are Air Force. While active duty people don't get matching funds, you still have some great opportunities to save for your future.
The L2040 is a great place to be for a young guy like you. I have a thread here that you may want to read- it's not designed specifically for military folks- but the theroy is the same- invest what you can afford now, and then some, and you will be much better off in the years ahead:

Bottom line is:
1. pay yourself first,
2. Dont' try and move around too much right off the bat. That's a mistake many make when first finding TSPTALK. You have to learn discipline first, and understand the drivers of the market, before even thinking about trying to better the market. Yes, it can be done- but you need to learn a LOT first before you try.
Watch, learn, practice, see what you are comfortable with, but by all means keep an eye on the markets overall, and be ready to manage your own future.
Learn about other ways to do things to- think about when you are going to need the money, and look into a Roth IRA, and see what that might do for you as well. At age 27, you have lots of time to build wealth, and buid for your future.
Good luck- and thanks for your service.
