After watching “Saving Private Ryan”, i began to wonder that are the different groupings for the army(company,squad,etc), and how are they determined? stictly by numbers or by talents, etc. and if any of you know the different ranks, that would also be helpful
I will presume you are referring to the U.S. military?
Keeping in mind that each branch uses a slightly different organization (and these can be further altered within the branches as well) this site gives you the Army basics.
And here for Marines.
Through these sites’ links you probably can find all else military (U.S.) that you need.
