My apologies for not giving you guys some context. Unfortunately, I don't have much to give you. This is the serial number on my grandfather's Tamgha-e-Jang medals of 1965 and 1971(non-operational service). He was in the 602 EME Workshop of the Pakistan Army. The workshop at the time, apart from military vehicles, maintained the vehicles of the presidential convoy. I think he was part of the security detail of the compound.
