Germany’s Southwest Africa colony (Deutsche Sud-West Afrika, DSWA) was defended by a security force made up completely of German troops. These troops were known as Schutztruppe and were all mounted infantry supported by artillery crews.
This crew, pictured below, consists of one gunner holding a shell, one with a bar, and two pushing the wheels. The 77mm guns were not recoilless, so the guns would be manhandled into position and re-positioned after each firing.
The bar comes as a separate piece from the gunner and can be glued into his hands. Alternately, if desired you can make a stiffer bar from a paperclip or similar metal.
NOTE: All figures are sold plain (not primed or painted) and without additional basing.
