The Marine Corps announced Thursday that six of the seven Marines killed in last night's midair helicopter collision near Yuma, Arizona, were from Camp Pendleton. Both helicopters were from also from the San Diego base.
The exact location of the crash has not been identified, but it is believed to have occurred on the California side of the Yuma Training Range Complex, according to the L.A. Times.
Situated near the Chocolate Mountains, the training area offers helicopter crews a terrain and temperature similar to what they might experience in Afganistan. Officials said the seven were training for possible deployment.
Names of the deceased and squadron information will not be released for at least 24 hours per standard Marine policy. The attack helicopters involved in the crash were identified as a AH-1W Super Cobra and a UH-1Y Super Huey and were part of the 3rd Marine Aircraft Wing, whose headquarters is at the Miramar Marine Corps Base.
