So, let's speculate.

My vote:  our 38 year old father of 2 from Washington will be revealed to be a born again Christian.

[UPDATE]

In the comments, I generalized (from memory) the nature of US Army enlistees.  Here's what the US Army has to say, as of 2009;

Does any region of the country provide more recruits than the others?

USAREC successfully recruits in all regions of the United States. The Army is significantly over-represented for enlistments from the South Atlantic, West South Central, and Mountain Divisions. Nearly ½ of FY09 Army enlistments (46.5%) are from these areas.

• The Army is significantly under-represented for enlistments from the New England and Mid Atlantic Divisions. Only 12% of Army enlistments are from these areas, even though over 18% of the youth population resides here.
• Army enlistments in the remaining Census Divisions (East North Central, West North Central, East South Central and Pacific) are representative of the youth population in those areas.

Do you recruit more individuals from small towns/rural areas than from urban areas?

The U.S. Army’s recruiting cohort closely mirrors the society from which it is drawn. The average recruit comes from a community that is slightly less densely populated than average for the United States. There is some under-representation of youth from most urban areas of our country in the enlisted ranks. The enlisted Army recruit population is skewed more toward rural and suburban areas than is the total population of 17-24 year old youth in the United States. This results in an under-representation of youth from the nation’s most highly urban areas. An increase of approximately 3,400 Army enlistments from these urban areas would be needed to bring the distribution into tolerance.
