Your question is far too broad to answer. If the war is near where police officers are working, they are exposed to the hazards of war, have problems keeping traffic moving with refuges, looting, etc. If the war is somewhere else, police may have shortages of staff, fuel, vehicles, and increased crime from black marketing, theft due to shortages of things for sale, crime from sabotage, etc.
what did the police do during the civil war?
The SS or Schutzstaffel developed AFTER World War I, so the question is inapt. In World War II, the SS police was a Nazi paramilitary police force.
Germany's secret police were the "SS". 2nd world war Germany's secret police was " Gestapo " you can pronounce like gastapo.
