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
