On April 30 the Marines of the 24th MEU, teamed up the UK's 16 Air Assault Brigade, began to push south of Garmsir. In a complex set of maneuvers, they conducted their passage through British lines and across the Helmand River where, but for a few border security police, neither ISAF nor the Afghan Security Forces have a presence.
Other British units provided planning, intelligence, engineering, and artillary support.
"This is what alliances are all about, professionals coming together to achieve the right effect," said Colonel Pete Petrozio, Commanding Officer of 24 MEU.
