I was thinking of a milkjug full of white gas with a road flare attached to it. Light the flare and heave the jug at the enemy. You'll scare them out of whatever crack they are hiding in and you'll know that they are bad guys later because they have no eyebrows.
Just joking. These are great ideas. what are some other tools you guys use? I was trying to mod one of those yellow grenades (DOLLAR STORE) with the big metal ends to have a hammer that would strike the cap and set if off. Problems were GIANT metal end and I could only come-up with a way of attaching a string and throwing the grenade to set it off. It would look more like fishing than milsiming.
