The Pentagon has significantly reduced the number of faith groups recognized within its personnel and administrative systems, eliminating more than 180 entries from a list previously used to identify service members’ religious affiliations. Defense officials said the changes followed a review that found numerous duplicate, outdated, or infrequently used categories. The updated system consolidates many denominations and traditions into broader religious classifications while maintaining that service members' rights to practice their faith remain unchanged.

Among the faith groups reportedly removed as standalone categories were various Pagan traditions, Heathen groups, Wiccan denominations, Druid organizations, Humanist affiliations, and a number of smaller Christian, Jewish, Buddhist, and spiritual movements. Many of these groups have not disappeared entirely from military records but have instead been merged into broader classifications. The Defense Department has argued that the revisions are administrative in nature and are designed to simplify recordkeeping rather than restrict religious expression.
