casualties in the War on Terror By mid-2015 each Ranger battalion had completed its 20th deployment in support of both Afghanistan and Iraq operations. As of 28 March 2016, since the War on Terror began, 31 Rangers from the battalion have been killed. Ranger and Afghan Commando joint raid against ISIS On 26 April 2017, 50 Rangers from 3/75th joined 40 Afghan commandos to conduct a joint US-Afghan raid in Mohmand Valley targeting the headquarters of Abdul Hasib, the Emir of ISIS-K, in a village in Achin District, Nangarhar Province, Afghanistan. The force was flown into Mohmand Valley and within minutes was engaged in a heavy, close-quarter firefight. AC-130 gunships, Apache helicopters, F-16 fighters, and drones were called in to support the fierce firefight with ISIS-K militants. The firefight lasted three hours, resulting in two Rangers from C and D Companies dead (possibly caused by friendly fire) after being medevaced and a third wounded. Thirty-five ISIS-K militants (including Abdul Hasib and an unspecified number of ISIS-K leaders) were also killed.
