One of the first experiences for all military personnel is putting together their personal information, including a statement of their religious preference. All Presidential candidates, who would be the Commander in Chief of our military forces, must undergo a de-facto test to ensure they have strong Christian faith. While unconstitutional, this is the reality in practice. Our military has a strong cultural bias toward Christianity as well. This is mitigated by accommodations for religious freedom, but the cultural bias is known. Especially within the disciplined, team environment of the military, there is strong pressure to conform with the majority.
