You almost never hear it these days, certainly not as a means of the individual trying to gain personal advantage, 50 yrs ago it was common enough for a manager to be Major this or Captain that, or an estate owner to be the Brigadier or General.
These days uniformed types dress down into mufti immediately in the UK and don’t use their title, there are disadvantages to that, knowing in advance who you are speaking to influences what you say.
