I tell you I didn’t understand the no religious preference/not listing a preference at first, but then after reading some articles I found that this was not uncommon — not to say that’s it’s done a lot, because I did not find that in my research.
I’m assuming people of faith (various) can choose this option for their own reasons.
A military person would have to verify that.
My suspicious nature tells me that some may want to fly under the radar by not listing a preference.
