During the Army's expansion following the September 11, 2001 attacks, Task Force 1-501 was expanded into an airborne brigade.
Flagged as 4th Brigade Combat Team (Airborne), 25th Infantry Division, the unit is now the primary strategic response force for the Pacific Theater.
 It comprises two infantry battalions, an engineer battalion, one cavalry squadron, a small artillery battalion, and a support battalion.
A full range of family and soldier support facilities common to any small Army community are found on post, ranging from a shoppette to childcare and recreational facilities.
The post has small but modern dental and medical clinics, and receives major medical services from the 3rd Medical Group hospital at Elmendorf.
The Joint Military Mall, also located on Elmendorf, provides post exchange and commissary services.

The post’s largest military tenant is the Alaska National Guard, with facilities at Camp Carroll and Camp Denali.
Fort Richardson also hosts several non-military activities, including a United States National Cemetery and a state-owned fish hatchery.
According to the Fort's website there are 5,418 soldiers, as well as over 8,300 family members housed at the base as of June 2008.
 The Fort also employs about 1,200 Army and DOD civilian employees.
Fort Richardson's military payroll for fiscal year 2003 was $85 million.
The civilian payroll was $49 million.
Including other expenditures of $111 million, Fort Richardson put more than $245 million into the local economy.

The fort encompasses 84,000 acres, which includes space for offices, family housing, a heliport, a drop zone suitable for airborne and air/land operations, firing ranges and other training areas.
Nearby mountain ranges offer soldiers the opportunity to learn mountain/glacier warfare and rescue techniques.
