What are we in year 12 of this bullshit...??? (CNN) One U.S. soldier was killed during a joint U.S.-Afghan Special Operations mission in Afghanistan, two U.S. defense officials told CNN on Tuesday. Defense officials said a medical helicopter was hit by mortar while on the ground but was able to take off. The incident occurred in Marjah in Helmand Province. Additionally, two U.S. service members were wounded. No additional details have been offered. "We can confirm a U.S. helicopter has landed in Marjah, Helmand Province, and is experiencing mechanical problems. It was not shot down," said Resolute Support Public Affairs Director U.S. Army Col. Michael Lawhorn. Another military spokesman expressed condolences on the death of the U.S. service member. "We are deeply saddened by this loss," said Brig. Gen. Wilson A. Shoffner. "Our heartfelt sympathies go out to the families and friends of those involved." Taliban fighters have made major inroads of late in Helmand, including taking over the key district of Sangin late last month, local police chief Mohammad Dawood said. Mohammad Jan Rasolyaar, the deputy governor of Helmand province, around that time wrote an open letter to President Ashraf Ghani warning that the province could fall to the Taliban if the Afghan government didn't step up its efforts there.
