When employing generic HEHC ammunition:
- Apply full EXP-DMG and add +1 dice rolls (3*10d20 -> 4*10d20).
- Reduce the weapon to 2 PEN.
- Do not calculate fragmentation (Exp. Rules NF).
As HEHC Shells are Explosive, their PEN is not affected by distance.
High Explosive, High Capacity is a type of shell made out of thin steel, maximising the amount of explosive filler contained. These were extensively used to grind down static fortifications during both World Wars, but also by the German Luftwaffe in its infamous minengeschoß autocannon shells. However, because they were made by drilling out solid shot instead of casting like normal HE shells, HEHC tends to be more expensive.
