The Balkans were just generally on fire in the 90s and NATO enforced a no fly zone and sent peacekeeper forces after the fact.
There's a few more peacekeeping missions and no-fly zones (Lybia for example), then some training missions, some humanitarian missions (Pakistan for example), a few air campaigns against non-state entities ("terrorists" but realistically that's often just a matter of perspective), and a bunch of anti-piracy actions.
So it's "every single war" with heavy emphasis on single.
