troop type specialising in IFV combat, called "Panzergrenadier". All mechanized and motorised infantry in the armoured force were reclassified as such in 1942, changing their classification from infantry to armoured unit. Sweden also adopted the Panzergrenadier doctrine in 1942, to some extent independently, although lacking dedicated infantry fighting vehicles until 1943. German Wehrmacht Forerunners (Schützen) The term Panzergrenadier was not adopted until 1942. Infantry in panzer divisions from 1937 onwards were known as Schützen (literally in German: Gunners) Regiments; they wore the same rose pink piping on their uniforms as the tank crews (with an "S" cypher that distinguished the Schützen from the tank and anti-tank units that also wore that colour). Soldiers in special Motorized Infantry units wore the standard white piping of the Infantry. In 1942, when Infantry Regiments were renamed as Grenadier Regiments by Hitler as a historical homage to Frederick the Great's Army, the Schützen regiments (and the soldiers in them) began to be redesignated as Panzergrenadier regiments, as did Motorized Infantry units and soldiers. Their Waffenfarbe was also changed from either white (in the case of Motorized Infantry) or rose pink to a meadow-green shade previously worn by motorcycle troops. Some units did not change over their designations and/or Waffenfarbe accoutrements until 1943, and many veteran Schützen ignored regulations and kept their rose-pink until the end of the war. Wehrmacht Panzergrenadiers during World War II The term Panzergrenadier had been introduced in 1942, and was applied equally to the infantry component of Panzer divisions as well as the new divisions known as Panzergrenadier Divisions. Most of the Heer's PzGren. divisions evolved via upgrades from ordinary infantry divisions, first to Motorized Infantry divisions and then to PzGren. divisions, retaining their numerical designation within the series for infantry divisions throughout the process. This included the 3rd, 10th, 14th, 15th, 16th, 18th, 20th, 25th, and 29th divisions. Others, such as the Großdeutschland Division, were built up over the course of the war by repeatedly augmenting the size of an elite regiment or battalion. The Waffen-SS also created several PzGren. divisions by the same methods, or by creating new divisions from scratch later in the war. A number of PzGren. divisions in both the Heer and Waffen-SS were upgraded to Panzerwaffe divisions as the war progressed. The Panzergrenadier divisions were organized as combined arms formations, usually with six battalions of truck-mounted infantry organized into either two or three regiments,
