No. NATO deployed some forces in Afghanistan as a result of the triggering of Article 5 in response to the 9/11 attacks, though it wasn't an all-out action and wasn't carried out through NATO's command structures. NATO did not deploy offensive forces into Iraq as an organisation. Some NATO members did on their own accord outside of NATO, but the organisation itself only ever had a non-combat training and advisory mission.
