Unlike its late introduction in the game, historically Howitzers were a fairly early development: "In the middle of the eighteenth century, a number of European armies began to introduce howitzers that were mobile enough to accompany armies in the field. Though usually fired at the relatively high angles of fire used by contemporary siege howitzers, these field howitzers were rarely defined by this capability. Rather, as the field guns of the day were usually restricted to inert projectiles (which relied entirely upon momentum to achieve their destructive effects), the field howitzers of the eighteenth century were chiefly valued for their ability to fire explosive shells. Thus, there were many cases where, for the sake of simplicity and rapidity of fire, dispensed with adjustable propellant charges."
