This sound is from Space Marine Chaplain - Warhammer 40k Soundboard

A Chaplain is a specialist officer of the Adeptus Astartes and serves as the appointed spiritual leader of a Space Marine Chapter. Chaplains are the warrior-priests that minister to the spiritual well-being of their fellow Battle-Brothers, instilling in them the values and beliefs of the Chapter and promote the veneration or in rarer cases the actual worship of the Emperor of Mankind.
