Panzer I
Although the Panzer I would participate in almost every major Nationalist offensive of the war, the Nationalist army began to deploy more and more captured T-26 tanks to offset their disadvantage in protection and firepower. At one point, von Thoma offered up to 500 pesetas for each T-26 captured. Although the Panzer I was initially able to knock out the T-26 at close range—150 meters (165 yd) or less—using an armor-piercing 7.92 millimeter bullet, the Republican tanks began to engage at ranges where they were immune to the machine guns of the Panzer I.
