The Subhas Brigade, or the 1st Guerrilla Regiment was a unit of the Indian National Army (INA). The unit was formed in 1943 and unofficially referred to as Subhas Brigade after the Indian independence leader Subhas Chandra Bose, who at the time was also the supreme commander of the army. The unit was the first and major commitment of the second INA in the Imphal Offensive, and along with Azad, Gandhi and Nehru Brigade, the Army's contribution to the Imperial Japanese Army's U-go offensive. Bose himself did not wish to have the Brigade named for him, but the name was kept.
