"World of New Krypton, Part Three"
Green Shield 24. Continued from Superman (1939) #687 and continues in Action Comics (1938) #877.
*With Superman now drafted into New Krypton's Military Guild, it seems that General Zod finally has the Man of Steel under his control. But when given a command to commit an act of brutality against his fellow Kryptonians, Superman must choose between following orders and following his conscience – at the risk of being branded a traitor by his own people! *Source: dccomics.com
