Not real tear gas; just taking the spray out of some axe; filling it with water and make a mechanism for a continuous spray; those within a 5 meter radius are "disabled" as rules for the game? With fake (or real) gasmasks to "defeat" this "grenade"? Can be used to clear enemy posisition or base/rooms What are your thoughts? Suggestions? Battlefield effectiveness? Cost per canister? Versatility?
