E Contingent, Hong Kong Police [1930-????]
This was made up of Russian policemen:
The problem of piracy had always plagued the waters of Hong Kong for some time when, in 1930, the British armed forces in Hong Kong decided to stop escorting the vessels plying the waters around Hong Kong. This mission naturally fell on the shoulders of the Police Force, which formed an Anti-Piracy Guard by recruiting 25 White Russians. The Police Force classified these Russian policemen as Group E.
