AFAIK there is not a straight HE round in widespread use for the 120mm guns of the L44 famility. The USA has MPAT, but that is an HEAT round fitted with a discarding sabot and a proxy fuze. Basically a jack of all trades master of none meant to be used against helicopters, low end AFVs (in a pinch) and soft targets. The israelis have worked on an APAM round, but that is a submunition antipersonnel round, not classic HE. IIRC some nordic nation had modified some 120mm mortar shells to be fired from the Leopard 2guns, IDK if it made into service.
I have never heard of something comparable to the OF-26 being adopted by 120mm users.
