It is true that Afghanistan was a direct consequence of the US triggering Article 5 following 9/11, so it makes sense that that would be considered a NATO mission.
Iraq is not a NATO mission on paper, but NATO allies backing up the US in Iraq is still an example of NATO allies backing up the US militarily as part of the unspoken agreement of NATO.
The US provides security guarantees for Europe, and in exchange Europe backs up the US in their escapades.

Stop pretending America’s allies did not do anything in Afghanistan. It is disrespectful to the veterans and those that lost their lives there.
