Working on a few bits as the wife and baby are gone tonight...First up, some IED markers for the 15mm moderns... the idea is that these may or may not represent bombs, and the NATO player would have to approach them with caution and defuse them, or risk explosion.
Then some "blinds"... I'll paint these with black shadow figures on them to represent "unknowns". When the player exposes them, they are replaced with innocent civilians, nothing... or bad guys!
