Much of the structure of the more modern German General Staff owed its existence and extensive structure to Frederick, along with the accompanying power of autonomy given to commanders in the field. According to Citino, "When later generations of Prussian-German staff officers looked back to the age of Frederick, they saw a commander who repeatedly, even joyfully, risked everything on a single day's battle – his army, his kingdom, often his very life." As far as Frederick was concerned, there were two major battlefield considerations – speed of march and speed of fire. So confident in the performance of men he selected for command when compared to those of his enemy, Frederick once quipped that a general considered audacious in another country would be ordinary in Prussia because Prussian generals will dare and undertake anything that is possible for men to execute.
