Yeah either HBG or any game store that sells Kaplow games mini poker chips same stuff. These interlock with the newer A&A games chips. My store let me bring some in and test it. I buy them in town for $3 Canadian 50 pack of chips. We just use the colour as a marker and stack the counter chips under them. Needed more counters than OOB global 40, so we bought 200 white as 1’s, 100 green as 3’s, 50 red as 5’s and 50 Pink for 10’s. The green and red don’t match the OOB shade so we replaced them.
There is a wide variety of Colours available but this is what we used. When we decide its worth buying a sculpt we can eliminate the Chips sometimes. First we just started with light and heavy for tanks but it has snowballed
Blue = marine, Marine armor, Seaplane
Brown = Mountain
Purple = Airborne
Orange = Damage (Was militia till we bought and painted sculpts for everyone from a single game of risk at a garage sale. Risk mini infantry and Cavalry pieces for all nations, at less than $5 Canadian.)
Grey(OOB) = (light or old tech). use it for TBD, Med. bombers, light tanks.
Yellow = (heavy/Advanced) Elite infantry, heavy destroyers, cruisers, tanks, advanced mech , sub etc.
Black = Country specific units like black shirts, Panzer grenadiers, Yamamoto.
Examples:
Super Yamamoto are yellow for advanced and black as designator combined
US marines are blue and Yellow.
We don’t use everything in there all the time. But we added them in the list from HBG sets. To see what interest the group had in any units. So far no German player has tried War plan Z but if there is enough interest we will shop on Shape ways, same for other items.
