The application may be accessed at: https://cmra.army.mil/Login.aspx.

The CMRA is an online database that automates the Army’s contract management and reporting process for contract management personnel by allowing users to enter their contract information, track contract data, and view reports based on contract data in the application. Its primary function is to support the Contractor Manpower Reporting (CMR) program that was approved on September 13, 2002 by the Business Initiatives Council (BIC) to improve the Army’s visibility of contractor services to planners and programmers. The CMR business process captures information of funding source, contracting vehicle, organization supported, mission and function performed, labor hours, and labor costs for contracted efforts. It enables the Army to:

• Fully understand the total Army workforce

• Provide better oversight of the workforce

• Ensure Army receives full value from contractor workforce

• Better account for total Army workforce
