They never fought in Africa, unfortunately. The kind of story you would need to make up would simply be the Belgian government sending Belgian army units to its colony (something it didn't do). Remember that Belgium didn't have a colony to send them to until 1908. That Carabinier uniform was worn at least as far back as the turn of the century (I have no info before then, but it probably goes further back), but the MG 08 didn't exist before 1908 and I'm not altogether sure when the Belgian army adopted it (I suppose you could just pretend it is a British Maxim).
One needs to consider that if they had been sent to Africa they would almost certainly have been given tropical uniforms too. Greatcoats
are great in Ostend in November, in the Congo, not so great.
