  • bombardment with TMF / REM ammunition packages according to Examples 2 and 3 has been dispensed with.

  • the projectiles In the bombardment tests, the projectiles first penetrate the cladding and several of the laminates during an angle bombardment, which reduces the kinetic energy of the projectiles and consequently slows them down. If its kinetic energy is too low to penetrate another laminate, the bullet will slide off the laminate.
  • the envelopes according to the invention are formed in the edge region so that such a projectile can be intercepted or stopped. As a result, the projectile remains within the envelope according to the invention and thus within the antiballistically effective package.
