“The losses of Matt and Forrest are a terrible blow to everyone who knew them,” said Col. Wolfe Davidson, 24th Special Operations Wing commander. “These two combat controllers were incredible warriors who not only volunteered to join our nation’s Special Operations Forces, but earned their way to the tip of the spear in defense of our nation.”

Roland was a special tactics officer at the 23rd Special Tactics Squadron here. He graduated from the U.S. Air Force Academy in 2010. Upon completing the rigorous STO training program in 2012, he was a team leader who supervised real-world combat preparedness training of a 35-member team. He deployed three times in his five years of service to multiple locations globally. He is survived by his parents.

Sibley was a combat controller at the 21st Special Tactics Squadron, Pope Army Airfield, N.C. He was a four-time Bronze Star medal recipient, once with the valor device, and he deployed four times to sensitive locations around the world in his nearly seven years of service. He is survived by his parents.
