The Salvation Army affirms the permissibility of military service for its members. Unlike historic peace churches, the Salvation Army places no prohibition on members serving in armed forces. The organization itself is structured with military terminology and hierarchy, which founder William Booth chose deliberately to emphasize the serious spiritual warfare against sin and injustice. Members are called 'soldiers' and leaders are given military ranks.

This military structure and affirmation of military service reflect the Salvation Army's conviction that Christians may serve God through various vocations, including military service, provided they do so with integrity and Christian conscience. The organization's Orders and Regulations contain no prohibition on members serving in the military or law enforcement.
