Its unique battlefield mobility and high level of training have kept it in the vanguard of U.S. land combat forces in recent conflicts: for example, foreign internal defense and counterterrorism operations in Iraq, in Afghanistan, and in Syria, as part of Operation Inherent Resolve.

In the United States (US) Department of Defense, a beret flash is a shield-shaped embroidered cloth that is 2.25 in (5.72 cm) tall and 1.875 in (4.76 cm) wide with a semi–circular base that is attached to a stiffener backing of a military beret. These flashes—a British word for colorful cloth patches attached to military berets—are worn over the left eye with the excess cloth of the beret shaped, folded, and pulled over the right ear giving it a distinctive appearance. The embroidered designs of the Army's beret flashes represent the heraldic colors and patterns of a unit with a unique mission or represent the Army overall. The Air Force's beret flashes represent their Air Force Specialty Code (AFSC) or their assignment to a unit with a unique mission. Joint beret flashes—such as those worn by the Joint Communications Support Element and the Multinational Force and Observers—are worn by all who are assigned, given their uniform regulations allow.
