This has been bothering me for a long time. How is the military organized to function as well as it does? I mean that in I see a lot of pictures and stuff, of artillary batteries operating in certain areas, but they are support for the infantry (correct me if Im worng on any of this), so how do they support the infantry? Kind of a vague question; if a company of infantry is operating near a town, and there is, for whatever reason, a need for artillary, aerial, armored, seaborn, what have you, support, who supports them and by what means? Like if a company somewhere needs aerial support (or else that is only in movies), and they call in, who's to say that air support is not out supporting another unit, or under maintanance or not even in the area, same for land-based support units. Do they coordinate ahead of time an artillary, armored, etc. support for each particular mission? This may sound like a confusing question, I hope you guys understand what Im asking. If not, just let me know and I'll see if I can explain in better sense. Thanks.
