Grand Priory NATO is the only international Grand Priory. It owes this special status to its relationship to NATO and the Interallied Confederation of Reserve Officers (CIOR) and Interallied Confederation of Medical Reserve Officers (CIOMR). To become a NATO Knight, one must

  1. Be a commissioned or warrant officer of a NATO or allied country;
  2. Be a member of one's national Reserve Officers Association; and
  3. Attend at least two summer CIOR/CIOMR congresses. Investiture can occur at the second CIOR/CIOMR congress.

Grand Priory NATO does not accept transfers of Knights from other OSMTH national Grand Priories. We accept dual-membership in the GP NATO along with membership in the Knight’s national GP. This exists obviously to preclude any competition between GP NATO and the national Grand Priories.
