The unit includes Alpha, Bravo, Charlie, Delta and Headquarters (HHC) Companies, all located in Danbury.
The following year, 34 soldiers from the 411th deployed to the Guantanamo Bay Naval Base in support of humanitarian efforts for Cuban refugees as part of a Presidential Selected Reserve Call Up.
From December 1995 to January 1997, the 411th provided teams for peace implementation in Bosnia and Herzegovina called Operation Joint Endeavor.
Immediately following the 11 September 2001 attacks, members of the battalion volunteered to assist in recovery efforts at 'Ground Zero' in lower Manhattan.
This effort marked the beginning of the 411th's contributions to the Global War on Terrorism as part of Operations Noble Eagle and Enduring Freedom.
At Camp Arifjan, Kuwait, personnel from Alpha worked closely with Brigadier General Kern (352nd CACOM commander) and his staff in developing the final OIF Civil Affairs plan.
At Najaf, Alpha was reconstituted and it deployed teams in support of ongoing 2nd ACR field missions in villages surrounding the city.
On 22 April 2003, Alpha established the first civil-military operations center (CMOC) in Baghdad, located immediately behind the UN compound.
Alpha took the lead in establishing Baghdad's first Internal Displaced Persons (IDP) relocation area (then known as Hillsdale).
On 19 August 2003, Alpha was engaged during the terrorist attack by Jama'at al-Tawhid wal-Jihad (renamed the 'Islamic State' in 2014) on the United Nations compound in Baghdad.
While traveling north with the 3rd ID and the 82nd Division, Bravo conducted CA operations in ten major Iraqi cities including Najaf, Hilla and Karbala.
The unit provided cultural expertise, and was charged with developing the first program of instruction for Iraqi Army Civil Affairs.
The 411th coordinated Operation I CAN, which collected donations of over 20,000 tons of school supplies for direct distribution by maneuver battalions and the Iraqi Army to the children of Iraq.
The area encompassed nine major cities and thousands of smaller towns and villages throughout the four provinces in AO Liberty, a total of 28,300 square miles (73,000 km2), overseeing over one and half billion dollars in scheduled reconstruction projects.
Members of the unit also worked in conjunction with the Provincial Reconstruction Team throughout the city of Kandahar and in nearby rural areas.
