Take France for example, they have EC725 Caracal with AAR capability and commandos that exercise all the time. Likewise with Spain, they have some CSAR capability with their AS532/AS332 and frequently exercise. The Turkish Air Force take CSAR seriously with AS532UL Cougars they took delivery several years ago.
Recently the French went to Davis-Monthan AFB and went on the Angel Thunder CSAR exercise, their Caracals took on fuel from the MC-130J Combat Spears
