Start a Fastlane business. It sounds to me like (1) you're leaving the military after deployment and (2) you don't wanna work a job.
If you are leaving, then what you need to do is go live somewhere very cheaply. All you really need is a room with a bed, shower, Internet connection, electricity and a kitchen, a phone, and a gym membership. Depending on where you live you can live off of less than $1000 a month. Use whatever money you have to start a business. Doesn't really matter what kind of business as long as it's Fastlane and feasible within your budget with the money you have.
Spend every waking hour either eating, working out, reading, or working on your business.
Forget the ideas about stocks and REIT bonds or whatever. Just my opinion
