COLORADO SPRINGS — The sergeant in charge of one of the busiest Army recruiting centers in Colorado, Sgt. First Class Dustin Comes, joined the Army, in part, because his father served. Now two of his four children say they want to serve, too. And he will not be surprised if the other two make the same decision once they are a little older.

“Hey, if that’s what your calling is, I encourage it, absolutely,” said Sergeant Comes, who wore a dagger-shaped patch on his camouflage uniform, signifying that he had been in combat.

Enlisting, he said, enabled him to build a good life where, despite yearlong deployments to Iraq and Afghanistan, he felt proud of his work, got generous benefits, never worried about being laid off, and earned enough that his wife could stay home to raise their children.

“Show me a better deal for the common person,” he said.

Soldiers like him are increasingly making the United States military a family business. The men and women who sign up overwhelmingly come from counties in the South and a scattering of communities at the gates of military bases like Colorado Springs, which sits next to Fort Carson and several Air Force installations, and where the tradition of military service is deeply ingrained.
