One experience is experience youre gonna brag about having it. Two most of the alliance didnt participate, the only members who did were the US, Uk, and Poland for some reason. Thats only two of the founding memebers and three members total, Australia was also there. It was a massive operation done by pretty important nations Poland is the most important NATO member in the east of Europe, the US just is the most important member, and Britain is also pretty fucken important.
But all four of the countries involved have independent alliances with eachother seperate from NATO, yes their offensive capabilities are helped by NATO but that is only on the experience and equipment level. If NATO was actually directly involved id expect France and Germany to have been involved for example.
