the Roman Catholic Church and does not apply to or govern other Christian denominations.

The term Christian is usually applied to people who identify with trinitarian Christianity. But from the beginning of Christianity there have been various sects who identify as Christian because they follow the teachings of Jesus but do not/did not regard Jesus as divine, e.g. the Arians. Even today there are religious groups that identify as Christian, follow the teachings of Jesus, but regard him as a divinely inspired prophet, not a literally divine Son of God.

I would not regard Unitarians as Christian. The ones in my community include a variety of religious perspectives from various religions and models of spirituality.

In the end, though, it does not matter if a service member is Christian, Buddhist, Hindu, Muslim, Deist, any other faith, or has no faith. The Constitution guarantees freedom of religion or to have no religion.
