Heroics and Ros seems about as old and venerable as 6mm gets. They offered reasonable and varied figures for WWII at a time when even GHQ offerings of infantry were weak. They also provided vehicles, artillery, and aircraft in a rich variety so that one could purchase a range of reasonably interesting figures to go with whatever vehicles one had.
The metal tray used above was from an AOL and shows just how many figures can be crammed into a small space, a boon for people who do not want miniatures taking up every bit of storage available. The figures lack detail but are nevertheless distinguishable both for nationality and weaponry. My painting on these was crude and quick. I wanted to get a batch on the table at the time.
These serve well with Deluxe Squad Leader boards since these are standard quarter inch counters. The addition of actual figures does lend something to any game. The figures on top all show a (riderless) supply wagon, one of those details that always improves a game’s appearance.
Currently, these are available through The Last Square though like everything else, they also turn up on E-bay. Infantry often comes in multiple types including regular infantry, heavy weapons infantry, and paratroopers. Not to be overlooked are the very useful artillery crews.
