Deng Ai
The Wei general Deng Ai, who had been leading Wei forces to resist multiple Shu incursions along the Wei–Shu border since 255, voiced strong objections to the campaign against Shu. Sima Zhao worried that Deng Ai would embolden others to oppose the campaign as well, so he commissioned his registrar Shi Zuan (師纂) as a major under Deng Ai and ordered him to "persuade" Deng Ai. Deng Ai then changed his mind and supported the campaign.
