Does Castle doctrine apply to military housing?

Provost Marshall should be able to tell you.

I agree with those in the string who say to check with installation law enforcement or the JAG. If you're asking, "can I shoot and kill somebody breaking into my home to do harm to me or my property?", then this is a very sticky question. Service members shouldn't have private weapons in their quarters on some installations. Again check with law enforcement. In many cases State Law applies in post housing areas.

You are subject to the UCMJ. Under the UCMJ, you can be charged with murder if the act is considered unlawful. One of the elements that changes the act from unlawful to lawful is justified self defense, that is different than than the Castle Doctrine. Self defense requires you retreat from the situation if possible, the Castle doctrine typically doesn't. I am not a lawyer, but in my opinion, you are setting yourself up for failure if your intent is to rely on castle doctrine protecting you. If you can resolve with less than deadly force, you should. Even if it doesn't raise to the level of murder, manslaughter can still be charged even if you are provoked.
