Vietnam era air mobile artillery platform intended to allow for artillery firing positions to be established in terrain that would normally prohibit them such as marshes, rice patties, other soft terrain, or uneven terrain. The legs & feet of the platform have recesses designed for rare earth magnets to allow for the platform to be on its feet or in water line configuration. Remember when using the magnets that the poles need to be aligned properly so they attach to each other not repel each other.
