Sentinel

Sentinels are an organisational order used by the Covenant.

Characteristics
Many threats assail the Great Journey, from within and without. To this end, the Guardian classification guards the journey through faith and firepower. The Guardian classification are largely escort or reconnaissance vessels, made not to prosecute wars, but to defend from threats. These vessels may range from heavy escorts, protecting dedicated warships, to lighter vessels made to fend off pirates and the like. These ships often vary massively in role and capability, but are unified in their role of defensive vessels.
