After World War II the I.N.A was on the losing side and did not exist as a ground force anymore. . All it's surviving members were treated as freedom fighters by the Indian governement after independence, however none were reinducted into the Indian Army,thus as a force the I.N.A did not evolve into the Indian Army but ceased to exist. However the force that defeated it- the British Indian Army, was in existence and the officers and men went on to form the Indian Army. So it's hard to agree that the INA was a predecessor. Not when the Army that beat it went on to become the Indian Army.You can say it predated it , but it was not a predecessor to the Indian Army.
