Of course while thinking of what to use to make the markers I soon thought of other uses for which the use of a marker would be beneficial. One Idea was to put the markers to use as the markers for blinds.
During the Nightime sequence of the Rorke's drift game I plan on putting them to use to record the presence of the Zulus on the board but not within visible distance. So the British player will have to be careful or a possible Zulu attack on one wall could just turn out to be a few skirmishers causing a diversion.
Another idea I had was to paint up the shields in the different main colour schemes of the different Zulu regiments involved in the defence of the 1879 invasion. While it helps with unit recognition by 1879 most of the amaButhos contained mixed shield colours. This gives us another use for the markers, I can if needs arise mix up and use the Zulus I already have done to represent a different iButho and differentiate the different amaButho's simply by using the correct colour shield for the iButho I wish to depict in front of the mixed unit as a unit recognition marker.
The sixteen markers in their movement trays which I keep them in when not in use. Movement trays with a single shield placed with its back facing the opponent is used as a blind representing the possible position of zulu's during a game.
