A ballistic beam used in special purpose vehicle in which a core with kinetic energy absorbing strength is positioned inside, and the outer shell with shock absorbing property surrounds entirely the core. The core is made of steel or other alloys of iron, other metal, metal alloys, cermets, ceramics, or combinations thereof that are either treated or untreated. The outer shell can be made of fabrics and is made of glass fiber, carbon, aramid, polyamid, polyester, polyethelene or hybrids of these materials. Bullets or splinters can be stopped effectively and cannot penetrate inside the vehicle. It is also possible to achieve minimized weight of the ballistic grill.
