Here are some of my (double sided) counters I use for my platoon-sized Microarmor rules (scale is 100 yards a hex).
This is a 3 Battalion German Regiment, with mortars but minus the Regimental Guns (infantry and AT). Of course the left half is the front, the right half the back.
Double sided counters are really easy to make, just cutting them out can be a bit of a chore, as you have to be careful. If you have access to one of a good bread-board cutter, it helps a lot. Just make sure you mirror the backside when creating the sheet (pretend you are just folding it over and see if it matches up).
I've got the system for double-sided counters down pat. Maybe I should publish a HOWTO artcle with pictures if anyone is interested.....
