Finland
The Sotilaspoliisi ("Soldier Police") are the military police of the Finnish Defence Forces. Their emblem is a black armband on the left shoulder with the letters 'SP' in white. SPs have no power over civilians except inside military zones and installations. However, SP's can be used as temporary manpower when the regular police are undermanned. For example during the 2005 Helsinki athletics championships military police conscripts were placed all along the running tracks through the city to prevent the large numbers of spectators from obstructing the runners. In these cases they are given a limited amount of power over civilians, as the regular police needed the extra support to handle the large influx of tourists. As military police conscripts are trained with basic police techniques they are suitable for usage in instances such as these in Finland.
