This is more directed to the 105 MM users, 120 is such a mish mash of MPAT, HEAT and other geee wiz ordy. Danes had a true HE round for the Leo I they used in Bosnia. US used/issues a HEP/HESH round for use in the MGS Stryker. Brit/Commonwealth Folks liked the HESH round as both General Demolition round as well as Anti Armor round up until recently.
I like HEP for its duality function. I do however see the utility of a dedicated HE round. Nick Moran had far more experience then most With His Tank Company in Iraq and used MPAT almost exclusively. What saith the forum?
