Detection and Alert Markers

Several detection or alert markers for miniature wargames and board games.
Four different exclamation point markers and two different question mark markers.

I use them to allow partial detection or localization of "stealthy units" (snipers, predators, etc.).
Example:
- Stealth unit fails a one stealth roll - place question mark within 12" of actual unit's location.
- Stealth unit fails a second stealth roll - place exclamation mark within 6" of actual unit's location.
- Stealth unit fails a third stealth roll - place actual unit on the table.
