The 4th Airborne Brigade is a unit of the Argentine Army specialised in airborne assault operations. It is based in Córdoba, Córdoba Province. Together with the Ist Armoured Brigade, they make up the Rapid Deployment Force (Spanish: Fuerza de Despliegue Rápido - FDR).

The members of the unit wear the red berets of the paratroopers with unit badges.
The Yarará Parachute Knife is a specially made dagger issued to Argentine paratroopers with a handguard that functions as a knuckleduster. Current issue models come with an emergency blade in the crossguard.[2] During jumps, the knife is put in an easy-to-reach place, so it can be quickly used to cut some of the parachute cords in case of an emergency, such as the cords getting entangled.
