  1. 4:37 - Even with a shaped charge, the velocity of the shell pre-detonation is still going to add to the velocity of the metal jet that the shaped charge spits out.

  2.  @vksasdgaming9472  Adding the shell's 1 km/s forward speed (in reality likely considerably more, as the shell is going to be going faster, not slower, than a rifle bullet, due to the shell's higher ballistic coefficient meaning it gets slowed down less by aerodynamic drag) to the 10 km/s speed of the metal jet increases the jet's total speed by 10%, which results in a 21% increase in the metal jet's kinetic energy (remember, kinetic energy is proportional to the square of speed) relative to what it would've been if the shell were detonated while stationary, which translates into an equivalent 21% increase in the shell's penetration capability. Hardly "irrelevant".
