hi,

If your not interested in the stress and deformation of the bullet,
which is usual way, you can declare it it as *MAT_RIGID, rigid body.

And definitely , armour will be Deformable body, so you can
choose *MAT_24, or any piecewise linear plasticity model.

depending upon the values you have for stress and strain
definition.
