The brigade now included Dutch, Flemish and Norwegian volunteer legions.[3] In January 1943, the 19th and 21st Latvian Police Battalions were serving with the brigade; Heinrich Himmler changed the 2 SS Infantry Brigade into a Latvian Brigade and at the same time set the foundations for a Latvian division.[4] The existing 18th, 24th, and 26th Latvian Police Battalions were used to form the Brigade's 2nd SS Volunteer Regiment. They were then sent for training at Krasnoye Selo, where Himmler added the 16th Latvian Police Battalion to the brigade in February.[4]
