What else but a paint grenade allows you to mark players in a 30ft diameter? The M-12 by BT allows you to easily deal destruction by simply pulling the pin (while holding the cap) and throwing it at or near the enemy. Upon impact the paint explodes outward in a spiral dealing destruction in a 30ft diameter. The RPS fill used in paintballs such as Marbillizer and EVIL clearly marks with a canary yellow fill. Best of all the RPS fill is safe on the environment and your enemies.
