LEXINGTON — An increasing number of cadets graduating from Virginia Military Institute are joining the military, and more are serving even before they graduate.

U.S. Secretary of Defense Robert Gates recognized VMI for that today as he addressed the school's graduates.

"What a tribute to this institution and the values that it instills," Gates told 246 graduates. "For generations, VMI has graduated young people ready to raise their right hand and defend their homeland. This is something to be grateful for at any time period, but never more so than in a time of war."

Just over 52 percent of the Class of 2008’s graduates at VMI commissioned into branches of the U.S. Armed Forces on Thursday. And many cadets are serving with National Guard units in Iraq and Afghanistan even before they graduate.

At the same time, VMI is experiencing it’s lowest rate of attrition in a decade. That’s a testament, said retired Gen. J.H. Binford Peay, the school’s superintendent, to the willingness of young men and women attending VMI to persevere through its tough regiment of education, physical fitness and military training.

Gates said soldiers, political and civic leaders and public servants of all kinds are eternal optimists.

"We actually believe we can make the lives of others better," he said. "Whatever path you choose, the common denominator is that here at VMI you have learned the importance of public service and duty to your fellow citizens. Such service has never been in higher demand, or those duties more daunting."
