Maj. Gen. Peter Gersten, the commander of the Air Force Warfare Center at Nellis Air Force Base in Nevada, was relieved of command Sunday over allegations of an unprofessional relationship.

“The Air Force holds leaders to high standards and expects them to uphold the core values of the service at all times,” Air Combat Command spokeswoman Leah Garton said in an email. “There is currently an on-going investigation and additional details will not be released at this time.”

ACC commander Gen. Mike Holmes fired Gersten “due to a loss of confidence in his ability to command based on an alleged unprofessional relationship,” the command said in a Wednesday release.

Brig. Gen. David Snoddy, vice commander of the warfare center, has now assumed command. He will run the warfare center until July, when Maj. Gen. Charles Corcoran — who was already slated to be the center’s next commander — is scheduled to take over.
