I don't want to turn to dust because my neighbor had a ND. So no NUKEs or BIO weapons. Small explosives are iffy at best as far as safety goes.
Arms are weapons that can be readily carried. Ordnance is weapons such as artillery and explosives.
Other than that, if I want a guided missile and have the proper place to detonate it where no one else could be endangered or come to harm, then I see no problem with it.
