Glad that it was no worse than it was. As was said, take plenty of pictures of everything. I'm a bit confused though, did the other driver have insurance? If so, are you dealing with their adjuster? Just remember that if you are dealing with their insurance, you don't have to accept their offer. With your own insurance, you likely have an arbitration clause which makes it more difficult to get their stated value of the claim raised, but you don't have a similar agreement with other driver's insurance (assuming they have insurance). USAA has been a great company to deal with for us, but at the end of the day, they are in the business to make money and will have their interests in mind first.
I don't usually jump to recommending an attorney, but in your case, you might want to consider at least talking to one as you may end up with a rather complex claim. An attorney can help you navigate these waters to ensure you are treated fairly.
Good luck and thank you for your service.
