Army Regulation (AR) 670-1 Practice Test

The symbol that represents actually taking part in an assault landing—whether a combat parachute jump, a combat glider landing, or an amphibious assault—is the Arrowhead device. This small arrowhead is worn on the uniform to show that the wearer participated in those specific types of assault operations. It signals a direct, hands-on involvement in airborne, air- or sea-based assault missions.

The other options indicate different things. The V device denotes valor in combat, not the method of entry. Numerals and service stars relate to campaigns, awards, or unit credits, but they do not indicate participation in a specific assault landing.
