you have to provide it to the aerodrome handling agency...God forbid they ever buy their own
in Europe, in the Civ world, outside of major hubs and certain tourist destinations (Geneva, Grenoble, Malaga... Palma?) ambulance flights are so rare as to render it not worth providing support equipment or training to FBO staff.
In the US, FBOs are a bit better stocked in my experience, but even then there can be significant gaps in knowledge.
In my limited dealings with mil repatriations, they expect you to have your own kit and do your own thing anyway - perhaps this is how the mil works.
