Hi sorry for the delayed reply, yes I was military and in the early days of Iraq/Afghanistan we didn't have much access to the internet so I brought it with me.
Library or school in a remote village. There are computers (usually old computers), there might even be a LAN of some sort, but no internet (or very slow internet).
In those cases having local access to Wikipedia (and not necessarily just en; Kiwix has archives for all the languages) can be a great learning resource and reference.
