The correct answer to this open question is the following.
The impact of George Washington's experiences in the French and Indian War was of a young military officer that gained so much experience of the battlefield that later served him to lead the Continental Army -the Army of the 13 colonies- during the Revolutionary War. Although at the beginning of the war the Continental Army lacked military experience, during the Valley Forge Camp in 1777, General Washington received the assistance of Prussian military officer, Baron von Steuben, who trained the Continental troops that later defeated the English soldiers to win the Revolutionary War.
