Induvidual soldier's salary

Recently one Non Commissioned Officer (NCO) of Territorial Army asked me what was the monthly salary of Indian Army of Second Lieutant in 1974? I replied, it was 1000 per month. We had to submit Income Tax return by physical mode.

Now NCO draw about 40,000 pm. He has to submit Tax Return. I was rembering in 1974 a soldier draw his salary when he will be going on leave. The amount accumulated in his salary account which was not getting any interest. Now the salary is credited in his Bank account, the family member can withdraw from their home town. The minium education for a General Duty Soldier was class VIII, now is Madhyamik.
