Admiral William McRaven, who leads the Special Operations Command, told a conference in Tampa, Fla. that members of elite units like the Navy SEALs and Army Rangers have proved prone to depression and self-harm over the past two years, reports Reuters. “And this year, I am afraid, we are on path to break that,” he said.

“My soldiers have been fighting now for 12, 13 years in hard combat—hard combat,” McRaven added. “And anybody that has spent any time in this war has been changed by it. It’s that simple.”
