Rogers' reflexes and senses are extraordinarily keen. He has blended aikido, boxing, judo, karate, jujutsu, kickboxing, and gymnastics into his own unique fighting style and is a master of multiple martial arts. Years of practice with his near-indestructible shield make him able to aim and throw it with almost unerring accuracy. His skill with his shield is such that he can attack multiple targets in succession with a single throw or even cause a boomerang-like return from a throw to attack an enemy from behind. In canon, he is regarded by other skilled fighters as one of the best hand-to-hand combatants in the Marvel Universe, limited only by his human physique. Although the Super Soldier Serum is an important part of his strength, Rogers has shown himself still sufficiently capable against stronger opponents, even when the serum has been deactivated reverting him to his pre-Captain America physique.
