Gov-Contract work. Need money advice

Hey all.

Going overseas for government contract work and will be making some decent money (70k/year tax free under FEIE if done correctly). Housing and car will be provided thankfully. How should I go about for investing or growing my money for however long I will be there, thoughts?

For context of me:
1. Single no kids. Late 20s
2. 25k debt from personal loan (consolidated all debt to make it easier for me, plan on attacking paying it off by December)
3. 90% VA disabled
4. 7k in savings

I Appreciate all input thanks.
