A technique in the sourcemod Empires which involves a grenadier dropping 9 mines in close proximity to each other. When the ninth mine is dropped, the first one explodes which causes a chain reaction and makes all the mines explode. This technique can be used to easily kill the enemy commander because it is a one hit kill.
