While we still don’t have a breakdown of Article 120 (2012) by elements, prescribed maximum punishments, or executive discussion (to understand why, read this and this), 31(b)log informs us that the Military Judge’s Benchbook has been updated to address the new Article 120, Article 120b, and Article 120c.
The updates should be accessible, without a login, here (at the bottom). If the link doesn’t work for you, please let me know.
Update: The instructions discuss mistake of fact as to consent as a possible defense to numerous offenses. Whether this defense is available was discussed by 31(b)log here (our post here).
