1. A totalitarian control over the lifestyle and time of its members - Many cults tend to dictate exactly what its followers should read, eat, how and with whom they should spend their time, and even what they should do in off hours.
2. A charismatic, self-appointed leader with complete authority - Cult members are taught not to question the teachings, practices, or ideas of the leader.
3. A focus on withholding truth from non-members - Many cults teach their followers to be completely open and truthful within the group, while at the same time they are encouraged to be secretive and evasive when questioned by people outside of the group.

On the other hand, they also apply to the Army Ranger (except for the leader being self-appointed -- and in the early days he was).
