UXO cards show the types of unexploded ordnance (UXO) most likely to be encountered in post-conflict situations. One of the suits is dedicated entirely to submunitions; also covered are grenades (hand, rifle and spin-stabilised), rockets, missiles, mortars, projectiles and MANPADS. Each card has a photo, information and specifications. As well as using them as conventional cards, they can also be used "top trumps", with images and specifications of the unexploded ordnance that threaten communities around the world.
