The common and multiple uses of this word indicate that it is a synonym for centralized. This article relies too heavily on the root being entrusted and basically downgrades the other uses especially in the introduction.
The commissary store is the central supply. The commissary officer is the centralized authority for a task or office. The officer is entrusted to centralize a process by the entrusting superior when they recognize that too much of the superior's time is taken up dealing with the issue from all the diverse sources. Thus the superior is relived of multiple interruptions through the process of centralization they now deal with one point of contact.
The use of the title "Metonymic Use" is obtuse and inappropriate. If continued to be used a link to http://en.wikipedia.org/wiki/Metonymy should be used.
The below quote is not clear. "most of the same" is not specific enough. The same what? Modern commissaries are quite similar to supermarkets, providing members with most of the same available in the U.S. economy regardless of where they are stationed worldwide. —Preceding unsigned comment added by 126.96.36.199 (talk) 02:00, 29 July 2010 (UTC)
