Don't think so ... I think BSD is a fictitious group meant to represent the BSF, which is part of the Indian Army ... anyone with an armed forces background, please correct if I am wrong.The foundation of the village Beerpur was laid by Tejawat ... in Rajasthan, there were literally hundreds of small princely states, some barely more than a few villages, each run by their Rajput 'princes'. They were at loggerheads with first the British, and then with the Indian Govt, which deprived them of their lands and their titles. So that could be part of the reason for the distrust and antagonism.
oh .. okay.
i hope there are more to learn of these officers in the coming episodes ...
