History
In May 2005 the ISAF Stage 2 expansion took place, doubling the size of the territory ISAF was responsible for. The new area was the former US Regional Command West consisting of Badghis, Farah, Ghor, and Herat Provinces.

On 9 October 2008 the Italian Brigadier General Paolo Serra took over command from his compatriot Brigade-General Francesco Arena.

There are currently four Provincial Reconstruction Teams (PRTs) under RC West:
 * PRT Herat – located in Herat, Herat Province and led by Italy. This is currently the command and control (C2) headquarters and the forward support base for the formation (Slovenian PRT is part of Italian PRT )
 * PRT Chaghcharan – located in Chaghcharan, Ghor and led by Lithuania
 * PRT Farah – located in Farah, Farah Province and led by the United States
 * PRT Qala-e Naw – located in Qala-e Naw, Badghis and led by Spain

The current Italian mission centers around the 2nd Alpini Regiment. Italy has sent 411 troops, based on one infantry company from the 2nd Alpini Regiment tasked to protect the ISAF HQ, one engineer company, one NBC platoon, one logistic unit, as well as liaison and staff elements integrated into the operation chain of command.
