The Order of Battle for the war games in the upcoming Herero War scenario and reference book by Jones and Alvarado calls for a fair number of German marines and an even larger number of sailors for the Landungskorps. I have the fine sets of the former from Copplestone and plan to add more from Pulp, but using these I will be stretched to provide the 36 figures needed to fill out 4 Marine sections (1 officer plus 7 marines in each), a senior commander, plus a 3 figure machine gun section. It can be done in 28mm without repeat purchases, but barely.
It is even more challenging filling out the sailors in the Landungskorps, for that will require 2 senior officers and a senior NCO (all on foot), six artillery figures with a machine gun and a revolver cannon, and 8 Landungskorps Units (1 Officer, 7 Sailors in each). This comes to 73 sailors and a large number of officers/NCOs, and while Brigade Games Great War in Africa series sets the standard and offers many of the figures this will require, it means purchasing multiple sets and a lot of duplication in the officer figures. Short of some careful surgery to swap heads and arms, this does not allow for much variation in sailor sculpts.
Luckily, there is another excellent option that will add 8-10 German marine figures, two 3 figure sailor gun crews with at least one usable machine gun, and a handful of sailors for the Landungskorps. All are in suitable uniforms, and all come in 25mm from Redoubt's Boxer Rebellion range. They are offered as single figures or gun crew sets. The German marines are from Seebataillon III and are fully compatible with their sister bataillons that were dispatched to Southwest Africa. The sailors are from Germany's strong ally Austria Hungary, and work well with those from Brigade Games. I plan to use some of them to crew my revolver cannon, probably the crew shown above with a Skoda machine gun.
