In the Army, anyway, there is. The Trial Defense Service is separately funded and supervised from the (prosecuting) Trial Counsels.
Does that fund allow the charged soldier to retain and pay his/her own counsel, independent completely of the military ? Or is it the equivalent of the Public Defenders Offices in civilian criminal courts, where you get an attorney appointed for you from a pool ?
If my soldier were charged, I’d want someone completely free of any overriding military influence, as in ... I’d want my soldier’s attorney(s) to be free to represent him/her without any thought of the attorney’s future regarding referrals or promotions, or any other benefit that could be offered or denied my soldier’s attorney(s).
