Currently, the implementation in ArmA 3 causes issues while trying to add custom grenades to units. You can override the existing class in a mod, however it will conflict with other mods trying to implement custom grenades. Please implement a way to add additional throw muzzles without having to override existing muzzles from the base game and other mods.

This problem seems to be persistent. There is no way, and no smart documentation, about creating custom smoke grenades. BI, you should add a status "old" for posts overshooting one year without any answer!
