The Profession of Arms Italian Il mestiere delle armi is a 2001 Italian film directed by Ermanno Olmi.
In a skirmish, Giovanni deMedici is wounded in the leg by a falconet shot. The attempts to cure him fail and he dies. The Imperial armies assault Rome.The film is beautifully but unassumingly set, and shows the hard conditions in which war is waged and its lack of glory. It ends straightforwardly with the declaration made after the death of Giovanni deMedici by the commanders of the armies in Europe of not using again fire weapons because of their cruelty. ........
