Drilling down though a Stack
Like most games of these kind, Panzer Campaigns has a limit in the number of men, gun or vehicles in a hex, and when more counters occupy the hex, the stack grows. This limit is 1600 men, but only the top four units are shown in the Unit Window, so using 3D Counters, a maximum of 4 counter is shown on the map.
The Counter values are of course only shown for the top unit of each stack. But if you left-click in the current Hot Spot hex, it will cause successive counters to be made transparent thus allowing you to see all of the counters in the stack in turn. If you left-click too quickly however, this will generate a double-click, thus restoring the stack and selecting all of the units in that stack via the standard interface method.
