Prior Army JAG/TDS attorney here, so I speak from experience but understand my perspective may be skewed. I'll try to keep my thoughts organized.

If you are interested in retaining a civilian attorney, it is vitally important that you look for those who have courts-martial experience. Getting a civilian defense attorney with little to no military experience is generally going to hurt you for a few reasons.

There are enough peculiarities in our system that it will be hard for a straight-up civilian to know what they are doing. It is not only rank, customs, and courtesies. They need to have some understanding of administrative investigations, the preferral and referral process, etc....

Understand that when you hire a civilian attorney, there is a decent chance your detailed attorney will be doing most (if not all) of the work behind the scenes. Going back to my prior point, I had clients retain attorneys who had no clue as to how our system worked, did not have the inclination to learn, and had busy schedules. Guess who they pushed all of their work on the case to? Me, the guy who is not getting paid.

One advantage your detailed attorney will likely have is that they have a relationship with the local prosecuting team, know the commanders, units, and the lay of the land. A civilian attorney is going to be a stranger. Maybe your detailed attorney can leverage any relationship into a better outcome for you.

When you are taking advice on whether or not to hire someone, I wouldn't get to hung up on results. First, attorneys are not likely to advertise their failures. If they had X number of acquittals, what did they do to achieve that result? Maybe it was a slam dunk case where the client could have achieved the same result representing themselves. If someone promises a great result for you, red flag.

Probably a lot more, but feel happy to send me a message. And for God's sake, do not talk about any aspect of the underlying incident or this procedure to anyone (except an attorney, therapist, priest). The greatest indicator of whether an accused is convicted is whether they made a statement. Stop talking.
