and actually managed to read Article 94 and its commentary:

Here's the full explanation:

(3) Failure to prevent and suppress a mutiny or sedition. “Utmost” means taking those measures to prevent and suppress a mutiny or sedition which may properly be called for by the circumstances, including the rank, responsibilities, or employment of the person concerned. “Utmost” includes the use of such force, including deadly force, as may be reasonably necessary under the circumstances to prevent and suppress a mutiny or sedition.
and the sample specification:

(4) Failure to prevent and suppress a mutiny or sedition.
In that ____ (personal jurisdiction data), did, (at/on board—location) (subject-matter jurisdiction data, if required), on or about ____ 20__ , fail to do his/her utmost to prevent and suppress a (mutiny) (sedition) among the (soldiers) (sailors) (airmen) (marines) (___ ) of ____, which (mutiny) (sedition) was being committed in his/her presence, in that (he/she took no means to compel the dispersal of the assembly) (he / she made no effort to assist _____ who was attempting to quell the mutiny) ( ).
The key words "prevent and suppress" do not deal with time period after the mutineers' surrender. At that point, the mutiny has been suppressed or quelled - and the mutineers are prisoners.

Labaan has a good point about tribes.
