RIP, Extortion 17:

August 6, 2016 marks five years since 30 American military servicemen and a U.S. military dog were killed when a CH-47 Chinook helicopter — call sign Extortion 17 — was shot down in Afghanistan.

Extortion 17 remains the greatest single loss of life since the Afghan war started in 2001.

Fifteen Navy SEALs from Naval Special Warfare Development Group’s Gold Squadron and five U.S. Naval Special Warfare support personnel based in Virginia Beach were among the victims.
