Is there a word (probably slang), that describes the slight state of shock common to new recruits in the first days (weeks) of military training, or the recruit suffering from that mild state of shock? I'm looking for a term that's slightly pejorative, but used in the understanding that the speaker has been there too. (The terms used in the Israeli Defence Forces for what I'm trying to convey translate as 'young' and 'open-mouthed'. I'm trying to express the same in English.)
I think I've seen "green" used similarly, in a Wild-West context (in a translation of Karl May), but I'm not sure whether it's used like that today.
