That is it the officer is the regular of this party and if you can get a look of his cap badge might give you a clue. There is a mix and match of the rest of the party they guy with the white coat is saying Belgium? but then you look into the others and there is a cross section I looked at their shoes/boots which is saying to me just after WW1 when after the conflict those who went home may not have got jobs so they looked into areas in which their past service could help them? which is why I said the Irish troubles and I am sure the officer is a police officer and the badge is the clue.
