What can I be doing now?

[Jordan Scott]

My name is Jordan Scott, I currently serve in the United States Army and have four years remaining on my contract. I have purchased a few books from Bigger Pockets authors and have become completely indulged in the Real Estate Investing world. I've always had an inkling for architecture, seems right in line with my interests. In a few months I'll be receiving a decent bonus from my MOS. My question is, I'm not sure if I should invest while in the military or save and go all in all after I ETS? I will be 27 years old at that time. Any advice is welcomed, thank you beforehand.
