Calculate the total time to produce explosives and explosive compounds.
Propelled Grenades are launched using Rocket Launcher skill and require a launch. Complex explosives skill can be used to build a launcher. A launcher requires 200 Total Effect Die in Complex Explosives to build.
Launcher Grenades require a grenade launcher, which is stand alone or underslung. Grenade Launchers are firearms and require that production path.
Missiles and Missle Launchers require a team, building them from scratch is unrealistic.
