 Any given strategic offensive is a derivative of a combination of factors such as national military doctrine, past military experience, and analysis of socio-political, economic and military circumstances.An offensive is a conduct of combat operations that seek to achieve only some of the objectives of the strategy being pursued in the theatre as a whole.Commonly an offensive is carried out by one or more divisions, numbering between 10–30,000 troops as part of a combined arms manoeuvre.
