High Explosive Squash Head is a very particular type of shell only really utilised by British tanks. It consists of an HEHC-like warhead filled with plastic explosives instead of conventional ones. These spread out over the impact area, forming a "pan" that upon detonation transfers a large amount of kinetic energy within the vehicle, usually resulting in chunks of deadly spalling flying off into the crew and critical components. Due to its immense explosive charge, it is also useful against fortifications.

Game Stats

HESH ammunition possesses Overpass, which means it always acts as if its PEN was equal to the target's ARM (wound on 4+).

However, this effect is only possible against solid plate such as Steel Armour or Aluminium Armour.
When targeting Composite Armour, this shell acts as a regular HE Shell of its calibre, but with No Fragmentation.

When employing generic HESH ammunition:

  • Apply full EXP-DMG and add +1 dice rolls (3*10d20 -> 4*10d20).
    • If the target is 4 ARM or greater, subtract -1 dice roll instead (3*10d20 -> 2*10d20).
  • Do not calculate fragmentation (Exp. Rules NF).

As HESH Shells are Explosive, their PEN is not affected by distance.
