War II on a musical tour with the USO promoting war bonds. He then uses that shield in his first combat mission. It is rendered useless after Johann Schmidt punches a large dent in it. He later notices an unadorned circular shield among Howard Stark's proposed weapons, which Stark says is made of a rare metal called Vibranium that is much stronger and one-third the weight of steel. Although Stark says it is a prototype, Rogers decides to use it after it stops .45 caliber bullets shot at it by Peggy Carter. It is painted into the familiar red, white and blue pattern modeled after the colors of the American flag. Rogers uses the shield throughout the war. It protects Rogers from not only standard weapons, but also the energy-based weapons Hydra uses that are powered by the Tesseract. Rogers also uses the shield as an offensive weapon and becomes highly skilled in accurately throwing, deflecting, and retrieving it. Rogers has the shield with him when he is frozen in 1945. In 2011, Rogers and the shield are discovered by S.H.I.E.L.D. agents in the Arctic within a crashed, frozen aircraft. In The Avengers (2012), Rogers uses the shield while fighting against Loki and is able to deflect an energy blast from his Mind Stone-powered scepter. The shield also guards Rogers from Thor's hammer Mjolnir, and the subsequent shockwave created when the two weapons collide causes both Thor and Rogers to fall to the ground and decimates nearby foliage. He also uses the shield during the battle against the Chitauri, and Stark deflects his energy beams off it to amplify their power. In Iron Man 3 (2013), Trevor Slattery is seen with a tattoo depicting the shield on the back of his neck. In Thor: The Dark World (2013), Loki's illusion impersonating Rogers also depicts a recreation of his shield. In Captain America: The Winter Soldier (2014), Rogers uses his shield while fighting against Georges Batroc and his men. It protects both him and Natasha Romanoff from a high powered explosive. during that mission, the red rings of the shield are painted a dull light blue, presumably for stealth. Restored to its original colours, he later uses it to crash through walls in an office building while chasing the Winter Soldier. When Rogers throws it at the Winter Soldier, he uses his metal arm to catch and throw the shield back,
