One of the issues I battled with this Orc army is how to keep track of all of the boys in the unit. Enter the simple and effective solution.
I picked up some customizable printer labels that you can peel off (here) for another project. For this, you simply cut down the label and put them on the underside of the base. Now you know where the guy goes and change the order over time (like for instance if GW changes the rules on you!).
Initially I used a Sharpie but it was hard to see (unless you have the super cool Silver Sharpie) and its hard to change.
There you go. Your simple tip of the day.
