Getting other state added in delhi License

[sa_ali]

Hi

I was planning to apply to add another 3 states on my license.
I was going through the delhi police site http://delhipolicelicensing.gov.in/arms/point-11.htm
In that its mentioned that for ppl working with Pvt Co, it should have
The designation and rank with area of operation handled by the employee from the owner/MD/GM of the company..
Now why is letter required from GM or for that matter Co itself, i am not asking it for official purpose, i am asking for personal reasons.
I can get letter of employement from the HR Dept
So any salaried class person undergone this process, pls help and obviously the legal gurus.

No one from delhi got other states added
Any help is appreciated.
I dont want to spend amount on getting NRI membership to make my case stronger
