What are the key heists in gta v story mode?

Grand Theft Auto V's narrative revolves around three protagonists—Michael De Santa, Franklin Clinton, and Trevor Philips—who engage in various criminal activities including heists. The 2013 Rockstar North game, set in San Andreas and Los Santos, positions these characters under pressure from corrupt government agencies and powerful criminals who task them with increasingly complex criminal operations. While the source material establishes that heists are a fundamental component of both the gameplay mechanics and story progression in GTA V, the specific names, details, and key moments of these heist missions are not documented in the provided verified evidence. The game is known for featuring several major heist missions as signature gameplay sequences, but without access to additional verified sources that enumerate these specific operations, I cannot accurately identify or describe the key heists beyond confirming their existence as core narrative elements.
