The Netherlands defense ministry has released photos showing the preparations for the large airmobile operation conducted Dec. 7 in Helmand province, Afghanistan, by mainly Afghan, American and British troops of the NATO-led International Security Assistance Force (ISAF). The airmobile operation and the supporting casualty evacuation mission involved approximately 20 Chinook, Black Hawk and Apache helicopters provided by British, Dutch and U.S. forces — meaning that practically all available helicopters in ISAF’s Regional Command South were used for the mission.
