Abstract: A tubular armor causes incoming projectiles to strike at a forty-five degree angle that induces vector alteration of the projectile upon impact. Its movement magnitude is reduced in force vector, momentum, and thus its kinetic energy. At least two facing layers of parallel tubes have a rectangular cross-section and are of a high ballistic material. The tubes are contiguously, fixedly disposed with respect to each other at outer opposed diagonal tube corners to form crests and valleys on opposed outer sides of each layer. The spaced layers have valleys of a front layer disposed over the crests of a back layer. Layer spacing is at an amount sufficient whereby when a projectile strikes the front layer facing a shooter, it compresses toward the back layer and transfers its kinetic energy laterally to follow a zig-zag path along the front layer.
