Why so few evangelicals in the military?

[Stranger in a strange land]

Evangelicals tend to be concentrated in regions with very high obesity and high dropout rates. I would guess that a lot of young evangelicals try to join the military but can't due to health and educational reasons.

Also, a lot of Evangelicals are "non-denominational Christians," though "non-denominational" doesn't necessarily mean Evangelical.
