The unit was dissolved after the collapse of the first INA. After the revival under Subhas Chandra Bose, the troops of the Hindustan Field Force formed the nucleus of the INA's 2nd division as the 1st Infantry regiment and ceded men to the 5th Guerilla regiment to form the 2nd Infantry regiment which later fought in the Battle of Irrawaddy and Battle of Meiktila under Prem Kumar Sahgal.
