SS-Panzergrenadier-Division "Reichsführer SS")[1] was a motorised infantry formation in the Waffen-SS of Nazi Germany during World War II.

In late summer 1944, a part of this division, SS-Panzer-Aufklärungsabteilung 16 (Reconnaissance Battalion 16), commanded by Major Walter Reder, was withdrawn from engagement with the American 5th Army then advancing on the Gothic Line to deal with an Italian Communist partisan unit, the Red Star Brigade (Brigata Stella Rossa).

[4] Together with the 1st Fallschirm-Panzer Division Hermann Göring the 16th SS Panzergrenadier is estimated to be responsible for about one third of all civilians killed in massacres in Italy during the war.

[2] In regards to these war crimes the 16th SS Panzer Reconnaissance Battalion and its commander, Walter Reder, have been identified as one of the main culprits.

[10] Major Walter Reder, the SS commander who signed the order to execute the civilians at San Terenzo, was extradited to Italy in 1948 and tried in Bologna in 1951 for war crimes in Tuscany and at Marzabotto in Emilia-Romagna, where 770 people were massacred, making it the worst massacre of civilians committed by the Waffen-SS in Western Europe during the war.
