I don't think you have to go that far actually. Since from what Ive
seen in research papers shock damage to ceramic steel sandwich shows
the damage/delamination/ceramic shatter area is > twice the projectile
diameter and HESH seems to deform to ~ twice its diameter before
detonation. Then the possible damage area is > 4 times this diameter.
So if we think of 120mm HESH, then thats a radius of > 25cm or an area
of ~1800cm^3. Put another way modern APFSDS mil accuracy is often 33cm
@ 3km so if you keep the cross hairs on the target and fire a APFSDS
after a HESH . You do have a good chance of hitting this shattered
area.
