Why not sum it up? It's all the same.
@Irvitzer Because they are not the same. This is another instance of a double entendre pun common in item names. This hinges on the double (practically opposite) meanings of the word "practice" (training vs. performing), as in the joke, "Why to doctors practice medicine? So, someday they might get it right." In the military, field practice means training maneuvers, i.e., training exercises in the field (which could be a forest, desert, or mountains; rarely farm fields anymore). In professions, field practice means performing your profession's activities away from the office. Clinical practice is sewing up lacerations in a sanitary, well equipped, and staffed clinic or hospital; field practice is sewing up lacerations in a ditch (for example); there are somewhat differing protocols for the two different contexts. For comparison, in social work, field practice is going out and meeting clients in their homes instead of at your office. I have returned the two meanings and have attempted to clarify the double entendre. Mikado282 (talk) 18:38, 19 May 2017 (PDT) Mikado282 (talk) 19:56, 19 May 2017 (PDT)
