Greenbaum is correct. Use can your Command Post address. If you don't know where that is, call the Base Operator, and ask to be connected to the Command Post. Ask them the address. 

For my I-129F, I did not use the Command Post address. I used the mailing address of the building I work out of primarily. It's equally as acceptable.

As far as where you have lived. I'm assuming you have lived in the Barracks/Dorms? You have two options:

Either use the Building/Room Number of where your barracks/dorms were. OR, call the Base Operator at your last base where you lived, and ask to be connected to that base's Command Post. Ask for the Command Post address there. This would include Basic Training, your Tech School, etc. 

When you asked if you should put your military branch HQ: That would be located in the Pentagon in Washington DC; so the answer is absolutely not. 

We just got our May I-129F petition approved! What a stress relief!

Although I signed up for Text Messages, they never texted me that it was approved.

So excited! Now for the next step.

Active duty here.

I'm not sure what you're looking for, in regards to your Active Duty status? It doesn't change anything in the slightest.

Anyway. If you want, you can message me and I'll answer any questions you might have.

Side Note: You said you just graduated boot. So you're in A School right now? If so, then I highly recommend you put this off until you get to your first Duty Station.

Anyway. Message me. I'll help you in any way that I can, brother.
