Final answer:
In the U.S. Army, only chaplains are authorized to wear their branch insignia on the Army Combat Uniform (ACU), centered on the blouse pocket.
Step-by-step explanation:
Branch insignia will not be worn with the Army Combat Uniform (ACU) except by one group: Chaplains. Chaplains are authorized to wear their branch insignia centered on the ACU blouse pocket. The insignia is traditionally a Christian cross, Jewish tablets showing the Ten Commandments, a Buddhist Wheel of Righteousness, or other symbols representing the chaplain's faith.
This is consistent across the various components of the U.S. Army, including Active Duty, Army Reserve, and the National Guard. The wearing of the branch insignia by chaplains is intended to provide religious support and spiritual care to soldiers, which is a critical function in the military environment.
