Yes, as of my last knowledge update in September 2021, the Army and the U.S. Air Force both use the Operational Camouflage Pattern (OCP) as their standard combat uniform. The OCP replaced the previous Army Universal Camouflage Pattern (UCP) and the Airman Battle Uniform (ABU) for the respective services.
The adoption of the OCP was part of an effort to standardize camouflage patterns across the U.S. military. The OCP is a multi-environment camouflage pattern that has become the standard combat uniform for the U.S. Army, Air Force, Space Force, and some other components of the U.S. Department of Defense.
It’s important to note that changes or updates to military uniforms and regulations can occur, so it’s advisable to check with official sources or the respective military branches for the most current information.
