The 52d Reserve Regiment remained a Brandenburger regiment, as at time of its formation. The 227th Reserve Regiment, formed in the 5th Corps District at the end of 1915, had a majority of effectives from the 4th Corps District and still received replacements from Prussian Saxony. On the other hand, the 232d Reserve Regiment, formed in the 4th Corps District, recruited principally in Hanover (10th Corps District). The 107th Division had hence a heterogeneous organization.
