Identifying Figures on the Tabletop
One of the worse things during a game is wasting time trying to identify which figure in a squad is armed with a special weapon or is the squad leader. In many games most figures are almost identical, apart from small details, or the figures are a small scale (such as my 15mm Gruntz army), this can be quite a challenge, especially on a larger table.
A quick and easy solution to this problem is to paint the base edges in a different colour from the regular troops. Depending upon the game system you can be as subtle of bold as you like with this, as long as it is noticeable under a quick scrutiny.
