WASHINGTON (MCT) — Before a roadside bomb in Baghdad burned and tore apart Jerry Majetich, before 62 operations put him back together, even before he volunteered for the Marines, then the Army, there were five older brothers who’d enlisted and a mother who’d served as an Army nurse in Korea.

His family background shaped former Staff Sgt. Majetich, who’s now 42, a single father and an investment firm vice president in Jacksonville, Fla. Despite the torment since the 2005 blast, that history is part of what moved his 21-year-old son to consider leaving college to pursue a military career, and his 17-year-old daughter to join her high school Reserve Officers’ Training Corps.

“I’d be thrilled if they chose to serve,” he said. “Despite everything, I believe in military service.”

This month marks 40 years since the United States ended the military draft, and an ever smaller slice of the population appears to share Majetich’s belief. Statistics are rare, but a Department of Defense 2011 Status of Forces survey indicated that
57 percent of active troops today are the children of current or former active or reserve members of the armed forces.

A recent Gallup poll showed that despite the wars in Iraq and Afghanistan, a much smaller percentage of those who’ve reached military age since Sept. 11,
2001, have served than in previous decades.

Part of it is simple demographics. While the U.S. population has grown since the draft ended in 1973, the military has shrunk. But this all-volunteer force appears to be passing from generation to generation, bringing up the worrying notion that the United States is developing a warrior class.

“The declining veteran population is one of our concerns, since there are fewer young adults in American society who are exposed to military service,” said Lt. Cmdr. Nate Christensen, a Pentagon spokesman. “While the armed forces continue to be largely representative of the country as a whole, nearly four decades of an all-volunteer force has shaped who is most likely to serve and from where.”

In the wide halls of the Pentagon, the military often is referred to as “the world’s largest family business.” The fear among some military leaders, politicians and experts
begins with the belief that as fewer segments of society have family or friends in uniform, others become desensitized to the risks and stresses of military service. The feared risks range from a reluctance to fully support those who serve to an almost cavalier willingness to wage war, reasoning, “That’s what THEY signed up for.”

Military and civilian officials admit that there are some positives in the smaller recruiting pool. The children of service members enlist understanding the job. They often were raised around the military and aren’t shocked by the culture, the level of expectations or long deployments.

Consider the Cotter brothers, who share a military life in the Flint Hills of central Kansas.

Several years ago, with college over and the recession in full swing, Gregory Cotter realized that his teenage dream of escaping the family business was a mistake.

“As a teenager, I wanted to do anything but this,” he said

But like his father and two brothers, he enrolled in the Army.

A tour in Afghanistan now behind him, Sgt. Cotter, 27, lives at Fort Riley, along with his twin, Andrew, a lieutenant, and their 28-year-old brother, Brian, a captain, both of whom served in Iraq. Their father, Col. David Cotter, retired not too far away, in Platte City, Mo., outside Kansas City.

“What we understood when we signed up is that this is a job, and we were raised to believe in serving something beyond ourselves,” Brian Cotter said.
