This happened in 50 Para Brigade Agra, just before V K Singh became Chief, sometime in Feb-March 2010, when he was Chief-designate. He was on rounds to some important formations as Eastern Army Commander, when he landed in Agra for a day and an orderly was sent to him. He sent him back after asking him his caste, and learning that the poor chap was not a Rajput !! Such strong is his caste-consciousness and they call army secular !!
